WHAT IS Tyre Seal?

A tyre life extender/conditioner & permanent puncture
prevention treatment
Tyre Seal is a special blend of polymers which coats and clings to the inner tyre. Tyre
Seal is a & quot;permanent" puncture prevention treatment and tyre life extender/conditioner.
Previously available products (and most current ones) have simply "fallen apart & quot; at
speeds of 40 mph and over, because they were manufactured for the construction
industries slow vehicles, but eventually made their way into the high-speed markets
creating problems. Tyre Seal is not a get you home product, it is applied before the
puncture occurs, and permanently seals punctures as they happen. Once installed,
Tyre Seal not only seals punctures, it conditions the inner casing, preventing porosity
leaks caused by tiny holes and cracks. In other words after installing Tyre Seal the
tyres maintain correct air pressure and the need to regularly top up with air is virtually
eliminated, and with correctly inflated tyres you get better fuel economy, your tyres also
run cooler eliminating that problem of heat build-up. Tyres treated with Tyre Seal last
considerably longer, and cooler tyres are also less susceptible to punctures. Tyre Seal
is water based for easy clean out if ever you need to do this and is installed in minutes
through the tyre valve with very little air loss and without removing any wheels.
What makes Tyre Seal different to tyre sealants that do not
work?
Technology! Sealants have caused many problems that we at Tyre Seal have
addressed. Using a highly evolved mixture of polymers, we have devised a product that
is more than capable of working in harmony with today’s modern breed of vehicles. We
use advanced chemistry in our process that bonds the molecules of the sealant
together at speeds up to 150mph. Previously available products, and most current
ones, have simply "fallen apart" at around 55-65mph.
Performance and abilities and does not diminish with speed
distance or time
Tyre Seal does not have any of the failings that previous and many present products
have. Apart from drying and balling up in the tyre, the biggest failings of traditional tyre
sealants in a high speed tyre, was the inability to seal small holes, but the ability to seal
a large dangerous hole or cut, because they contained large chunks of chopped up
rubber. Whereas Tyre Seal contains only tiny strands of coarse surface synthetic fibres
that are stronger than steel when they interlock tightly together, but will only positively
seal small holes caused by puncturing objects up to 6mm in diameter, but only in a hole
that is in the tread area of the tyre, and that is shrinking in size because there is no
cord damage (rubber recovery), which is 95% of today's punctures in high speed
vehicles. Anything bigger, or in the sidewall, with or without cord damage, and the Tyre
Seal fibres just slowly bleed through the hole, giving a controlled deflation, and usually

with a halt or abrupt slow down in air pressure loss at the lower pressures of 10 to 15
psi (depending on cord damage) which prevents damaged rims, and helps the driver
maintain control possibly enabling continuation of the journey to remove the vehicle
from a possibly dangerous location.
Through our extensive research and development, our proprietary formulation has
evolved far beyond that which is commonly known as a tyre sealant - Tyre Seal is a tyre
safety system outstanding at permanently sealing punctures and a true tyre life
extender. Tyre Seal converts any pneumatic tyre into a self-sealing tyre that will
maintain air pressure. Tyre Seal has the ability to coat more of the inner surface of a
tyre and rim without succumbing to shear and stress associated with centrifugal force
that is created within a high speed rotating tyre. Tyre Seal's attributes are unparalleled
in the history of the pneumatic tyre.
The Tyre Seal Research & Development Team developed an unrivalled proprietary
process that has yet to be duplicated.
How it works
Once Tyre Seal has been installed, it lies dormant at the bottom of the tyre until the
vehicle is first driven. Once driven a minimum of three to five miles, Tyre Seal disperses
throughout the inner tyre and forms a coating on the inner surface of the tyre assembly.
In order to get sidewall coverage it takes 1500+ miles to activate the FlexxaGel to
adhere to more of the inner tyre. The flexing of the tyre and the normal heat build-up
allows Tyre Seal to seek out and eliminate common air loss problems (referred to as
porosity, air migration and bead leaks). Tyre Seal then transforms the tyre assembly
into a sealed air chamber, capable of maintaining proper air pressure. Thereafter, Tyre
Seal conditions the rubber in order to retard dry rot and aging (hardening) of the casing.
One treatment will provide additional longevity and cooler running tyres for the legal
tread life of the tyre.
The advanced technological sealing capabilities of Tyre Seal stand on guard to seal
punctures as they happen. When a tyre is punctured, Tyre Seal coats the surface of the
penetrating object, thus preventing air loss.
When the puncturing object is removed, the rubber recovers and the wound
immediately closes, escaping air siphons Tyre Seal into the puncture. The fibres
entwine to create a clot that prevents any additional air from escaping. As the rubber
recovers, the puncture closes and the strength of the tyre holds the seal in place. The
specialised polymers and fibres form the seal, thereby producing an airtight seal. The
small amount of Tyre Seal that penetrates through the puncture, past the belts and out
through the tread area is referred to as a seal. Once exposed to the atmosphere, the
seal begins a systematic cure (another proprietary attribute from the Tyre Seal R&D
Team). As the seal cures, it makes a positive secure seal that is impervious to water,
which totally protects the belts and inner casing from outside contaminants and
corrosion.
Tyre Seal's proprietary formulation is one of our closely guarded secrets, which allows
Tyre Seal to withstand heat and the shear forces created within a rotating tyre. The
thixotropic polymers stretches and recovers under mild to severe exposure of the

adverse forces and continuously clings to the inner tyre. The ability to coat the inner
surface against adverse conditions and centrifugal force is the reason that Tyre Seal
will not adversely affect a balanced tyre assembly and does not lose the ability to
provide protection for the tread life of the tyre.
Tyre Seal's abilities & performance is not diminished with speed, distance or time.
Sealing capabilities
If the tyre's integrity is weakened to a point where the tyre and casing are unsafe, Tyre
Seal is designed to bleed and slowly release air pressure in a controlled way if the
puncturing object has severely damaged the inner structure.
Tyre Seal will not hide or mask a dangerous puncture regardless of how small the
damage may be. If the integrity of the casing has been breached and safety becomes
an issue Tyre Seal is designed to allow air to escape in a controlled manner.
Coating and conditioning
Tyre Seal coats and clings to the inner tyre conditioning the inner surface, eliminating
air migration caused by porosity and bead leaks.
It is imperative that the proper amount of Tyre Seal be installed in a tyre (refer to
application chart). In order for Tyre Seal to function, the vehicle should be driven
approximately 3 to 5 miles (it is not required to immediately drive the vehicle). This
initial driving allows the tyre to warm up and for Tyre Seal to distribute. Tyre Seal will
cover the crown area in the first few miles but it will take another 1500+ miles for the
FlexxaGel to activate giving more coverage of the sidewall. Unlike conventional tyre
sealants, Tyre Seal has been developed to prevent migration from the sidewalls and
the tread area at high speeds. Once the initial driving/usage period has been attained;
Tyre Seal cover more of the inner surface of the tyre.
Tyre Seal is a proprietary liquid coating that never deteriorates within the tyre and will
continuously stand on guard to protect tyres against air loss for the legal tread life of
the tyre.
Will not cure or harden inside the tyre
People often ask, "If Tyre Seal cures from exposure to outside air, then why doesn't it
cure by the air inside of the tyre?" Tyre Seal transforms the tyre and rim into a sealed
air chamber. As the vehicle is driven and the temperature of the tyre increases, a
portion of the liquid base vaporises within the tyre assembly's inner air cavity, as the
tyre cools, the moisture condensates back into the formula. The inside air actually
becomes part of the system. The sealed air chamber prevents outside air from entering
or inside air from escaping. Constant air pressure maintenance is not required.
Positive secure seal
When a tyre is punctured, Tyre Seal is forced against and around the puncturing object
by the inner air pressure, thereby preventing air from escaping. If the puncturing object
is thrown out of the tyre by centrifugal force or is pulled out, the inside air forces Tyre
Seal into the puncture and immediately stops air loss. Special fibres entwine, forming a
seal, then as the rubber recovers, aided by the tyre flexing as it rotates, the inner air
pressure forces the seal well into and through the puncture. Once Tyre Seal is exposed

to the outside air, a curing process begins. The cured seal extends well into the
puncture, thus providing a seal that is impervious to water (rain, snow, mud, etc.). As
this seal cures, it is transposed into a permanent rubberised seal, protecting the inner
casing and steel belts against contaminants entering the puncture.
The 80/20 syndrome
The seal is permanent because of two very important attributes of Tyre Seal:-
A/...there is no shrinkage of the drying polymer in the puncture because the gel is 80%
polymer and only 20% liquid because we do not use cheap ingredients that bind huge
amounts of water. It is common for similar products to be the other way round with 20%
polymer and 80% liquid.
B/...The gel dries and cures to a firm, flexible and rubber consistency which means the
seal will flex with the puncture causing no air loss over time.
It is a fact that any viscous wet compound containing fillers such as fibres and rubber
particles will initially seal a puncture whilst in the wet state because wet compounds will
flex with the tyre in the puncture, but the problems arise in many of these "so called"
similar products when the liquid escapes out of the puncture into the atmosphere
causing the compound in the puncture to dry back to the original ingredients. When
dried out these "so called" similar products will vary in looks and texture because of the
vast difference with ingredients used in these tyre sealants to such as:- Biscuit,
Plasticine, Putty, Paper, Crystalline, Flour, Sticky pritstick, Bluetack, cement, clay etc.
The descriptions and looks of many of these dried out products are neverending, but it
is a fact that in the wet state these gloopy tyre sealants all look very similar, except in
colour, but that is where the similarity ends. Many of these compounds that have
usually been formulated by people without any knowledge of chemistry whatsoever,
once dried out in the puncture will eventually fail, resulting in a flat tyre, sometimes
within days or just weeks after the initial puncture.
The eight images directly below are of Tyre Seal and six "so called" similar products
that have been allowed to dry out in a laboratory oven at 50 degrees C for 24 hours.
When fully dry Tyre Seal has very little shrinkage and is flexible and firm which is the
attributes required of a dried out tyre sealant in the puncture to permanently seal the
puncture, and especially in the low speed market were punctures can be caused by
puncturing objects up to 30 mm in diameter. It is our trademarked secret ingredient
"FlexxaGel™" that gives Tyre Seal so many of its quality attributes.

THE DIFFERENCE
At a Glance
ď‚· Will seal punctures permanently and for the life of the tyre.
ď‚· Will give you a controlled deflation if the integrity of the tyre has been
compromised.
 Will cover more of the inner tyre “at high speeds” to prevent porosity in the tyre
and stop bead leaks - Requires advanced chemistry.

ď‚· Will not pile up in a narrow band down the centre of the crown area owing to
centrifugal forces - This is a common problem with many sealants and the
advanced chemistry required to prevent this is our closely guarded secret.
 Will seal punctures over more of the crown area” owing to Tyre Seal’s “better
inner tyre coverage.”
ď‚· Will not seal punctures in the thin & flexing sidewall, but will give a tell-tale sign
with a controlled and slow deflation.
ď‚· Will help extend tyre life because of a much cooler inner tyre. Heat build-up is
removed by conduction away from the inner tread area to the rim, because of
better inner tyre coverage. Plus, cold tyres are less susceptible to punctures.
(Rubber is a poor conductor of heat).
 Will help extend tyre life as better coverage over the “inner tyre” eliminates
porosity giving optimised tyre pressures,with the added benefit of improved fuel
economy and safer vehicle handling.
 Will be manufactured using heat” in an intricate process with over 15 polymers to
give a solids content of 80% but only 20% liquid, rather than 80% liquid and only
20% solids which is common with sealants mixed cold with as little as one or two
polymers - You cannot achieve the attributes you find in Tyre Seal with only one
or two polymers or without applying heat and the principles of chemistry during
the manufacturing process.
ď‚· Will cure in the puncture to a firm and flexible rubbery plug, as opposed to
something resembling sticky modeling clay or hard and common with tyre
sealants formulated with just one or two polymers. These simple sealants initially
seal punctures, but then fail as the plug dries and shrinks because of heat. This
is because simple tyre sealants with a high water content that can bind fibre and
rubber particles whilst still in their liquid state, initially seals a puncture in a tyre
but fail as the tyre sealant plug dries and shrinks.
ď‚· Will be water based for quick and easy clean out from the tyre.
ď‚· Will definitely not vapourise or steam in a warm tyre causing the tyre pressure to
increase to a dangerous level - Requires advanced chemistry to achieve a
complex azeotropic liquid base that increases the boiling point of liquids to
prevent steaming. Similarly, when water binds the polymer chains via hydrogen
bonding it increases the surface area, which causes the water to evaporate out
of a polymer at the slightest increase in temperature. Our unique chemistry
prevents this from happening.
ď‚· Will not over any length of time, break down or dry up inside a high speed tyre -
Requires advanced chemistry applied with heat to achieve this.
ď‚· Will not over time lose any viscosity in the tyre.
ď‚· When heat and stress is applied to water based polymers inside a high speed
tyre, the polymers rapidly thin within a few thousand miles in a process called
hydrolysis (decomposition of the polymer chains owing to a chemical reaction
with water, during which molecules of water are split into hydrogen cations) Our
unique chemistry prevents this from happening.

ď‚· Will not ball up inside the tyre. Owing to the large difference in specific density
between the heavy liquid polymer and the significantly lighter fibre and rubber
particle solids, centrifugal force normally cause these lighter particles to be
forced in a reverse direction and collect on the inner surface of the polymer in
clumps. Our unique chemistry prevents this from happening.
ď‚· Will not run to the bottom of the tyre in a stationary vehicle.
ď‚· Will be thermally stable at speeds of up to 250kph - Very rare.
ď‚· Will not rust or corrode rims.
ď‚· Will condition the inner tyre.
 Will not void tyre manufacturers’ warranties.
ď‚· Will not contain Ethylene Glycol, an extremely toxic anti-freeze.
ď‚· Will be non toxic - A result of years of Research & Development.
ď‚· Will always comply with Health and Safety regulations in Europe and the UK.

WHY DOES

Tyre Seal Not Cause a Balance

Problem?

The law of physics are quite precise, especially when it comes to liquids in a centrifuge,
they will be forced in the direction of the forces, which in a moving tyre is in the
opposite direction from the wheel rim. A tyre on a moving vehicle is a centrifuge and
tyre sealants inside a tyre will obey these laws and be forced outwards to the highest
point which is the centre of the crown area as shown in diagram A below. As a vehicle
gathers speed, tyre sealants form a narrow band in the centre of the crown area of the
tyre and the width of this band is dependant on the vehicles speed. At only 2 miles per
hour that band will be narrow covering approximately only 70% of the crown area, but
as the vehicles speed increases to normal driving speeds of 20 to 60 mph that band
narrows significantly as the centrifugal forces increase. With these higher speeds a tyre
sealant will begin to pile up in a bulky mass as extreme forces come into effect as
shown by the arrows in diagram A. At these high speeds and with these conditions
balance problems are prevalent. Sideways movement of the vehicle will temporarily
cause a little sealant to creep across the shoulder area, but forward movement will
immediately bring it back again. Also because of the low crown coverage, even at
speeds of only 2 mph, there is no protection against punctures in the shoulder region of
the tyre as shown in the grey shaded area marked S in diagram A.
Tyre Seal covers more of the the inner tyre "at all speeds", yes from 2 kph to 250 kph
- better coverage, as shown in diagram B below and that gets better the more miles
the vehicle covers. As the vehicles speed increases, Tyre Seal's thixotropic polymer gel
stretches over the inner tyre giving good coverage with a very thin layer no thicker than
2 or 3mm, and that is the reason balance problems do not occur with Tyre Seal. (The
Tyre Seal gel will relax in a stationary vehicle covering less of the inner tyre) We at
Tyre Seal UK have managed to achieve this in a process using very advanced

chemistry not normally found in any other tyre sealant. Our proprietary process which
gives Tyre Seal these attributes and other beneficial properties is our most closely
guarded secret which no other manufacturer has yet managed to duplicate. You need
very sophisticated equipment to achieve this level of chemistry which we have had built
entirely to our specification. Large rubber particles of 1 mm in size normally found in
tyre sealants are also a big cause of balance problems. We granulate our own rubber
particles right down to between .2mm and .4mm for inclusion in our high speed grades .

Safety Features

The Main Safety Features of Tyre Seal
HighPerformance, High Speed Grade

Outstanding at sealing punctures
Tyre Seal’s makeup is 80% polymer and 20% liquid which means it is a very high solids
content and dries to a flexible rubbery plug in the puncture without any shrinkage. The
polymer gel suspends a special mix of highly fibrillated fibres and granulated rubber
fillers which contribute to Tyre Seal’s sealing abilities, so once the seal is in place it is
permanent and will not fail at a later date.
Seals only the smaller, less harmful punctures
Tyre Seal does not have any of the failings that are inherent in many previous and most
of the current products available on the market today. Traditional tyre sealants contain
large chunks of rubber particles that are incapable of sealing small holes in a tyre, yet
they will readily seal a large and dangerous hole or gash. Conversely, Tyre Seal
contains only small rubber granules and synthetic fibres that when interlocked in a
puncture are extremely strong. Tyre Seal will only seal punctures in the tread area that
are safe to seal and which have been caused by puncturing objects no larger than 6mm
in diameter and only if the hole is shrinking in size because neither excessive tyre
rubber has been lost or cord damage has occurred. These small punctures account for
95% of today’s punctures in high speed vehicles. Any larger puncture, either with or
without cord damage and Tyre Seal will just slowly bleed through the hole giving a
controlled deflation. In these circumstances air pressure loss in the tyre will either stop
or slow down at the lower pressures of 10 to 15 PSI, dependent on the severity of the
puncture. This slower loss of air pressure prevents damaged rims and enables the
driver/rider to maintain control and possible continuation of the journey, thereby
removing the vehicle from a potentially dangerous location. Tyre Seal will not seal a

puncture in the sidewall because the sidewall is much thinner and more flexible,
therefore in the event of sidewall punctures a controlled deflation will usually occur.
Gives better coverage throughout the inner tyre
Traditional tyre sealants do not cover 100% of the crown area in a high-speed tyre - at
best they usually only cover 60% which becomes less as the vehicle increases in
speed, because more of the tyre sealant is driven to the centre area creating a mound
that can cause vibration at the higher speeds. One of the components of Tyre Seal is a
polymer gel (FlexxaGel™) which has an affinity to adhere to rubber even in a vehicle
moving at very high speed. Although "FlexxaGel™" behaves like a glue and has
properties similar to glue, it is not a glue. When the lateral movement of a vehicle
throws the excess Tyre Seal over the crown area and sideways up the inner sidewalls
of the tyre, the adhesive properties of "FlexxaGel™" allows Tyre Seal to cling evenly
over more of the inner tyre surface at all speeds. Although the gel will immediately
cover the whole of the crown and shoulder areas, a settling in period of 1500+ miles is
required to activate the FlexxaGel™ for sidewall coverage. This maintained inner tyre
coverage at speed gives added heat dispersion to the rim via sidewall coverage due to
conduction. Heat dispersion to the rim allows a cooler inner tyre and cool tyres are less
susceptible to punctures. The gel’s ability to seal porosity leaks over the inner tyre
helps maintain tyre pressure, the tyre becomes safer with the added bonus of extended
tyre life. Incorporation of "FlexxaGel™" into the process also gave the finished sealant
incredible elastic properties enabling it to stretch and flex, covering more of the inner
tyre with increasing speed. (The Tyre Seal gel will relax in a stationary vehicle covering
less of the inner tyre) "FlexxaGel™" is exclusively manufactured at our Devon facility
and is one of our most closely guarded trade secrets.

Withstands the heat and stress in a high speed tyre
Unlike traditional tyre sealants, Tyre Seal's concentrated polymer gel formulation
containing over a dozen technically advanced polymers, rubber and fibre fillers, will not
separate, ball up, or dry up - thereby withstanding the extreme heat and centrifugal
forces that can be created in the hostile environment of a very high speed tyre. In a
closely guarded proprietary process, Tyre Seal is manufactured to stay liquid in a high
speed tyre for the entire lifetime of the tyre, irrespective of its use. Compared with
traditional tyre sealants, the Thixotropic qualities of the Tyre Seal polymers allows
change from a very viscous gel to a thin liquid when the vehicle is at speed, yet
returning immediately to a viscous gel when the vehicle comes to rest, and it is this
feature that helps stabilise the polymers from eventual breakdown. Many traditional tyre
sealants pool on the bottom of a tyre in a stationary vehicle causing vibration with each

forward movement, but Tyre Seal stays firmly coated over the inner tyre. Tyre Seal's
ability and performance is not diminished with speed, distance or time.
These qualities alone put Tyre Seal in aleague of its

own
WHY DOES

Tyre Seal Outperform Other

Sealants?

Tyre Seal is not like a tyre sealant, it is
"arevolutionary new product"

Why Tyre Seal performs, whilst others fail
Traditional tyre sealants are simple inexpensive products, formulated with as little as 4
ingredients, very similar to wallpaper paste, and containing particles of shredded tyres,
that "temporarily" clog up a hole in a tyre. When they are applied in a high speed tyre,
because of heat, and centrifugal forces, they break down, and dry up, thus rendering
them ineffective. This may be detrimental to the tyre in the long term, and they may
also rust or corrode rims, and steel belts. Whereas, Tyre Seal, is a "concentrated
viscous gel", consisting of many polymer gel ingredients in a comprehensive and secret
formulation, plus our specially manufactured “coarse surface” synthetic fibres, interlock
together in the puncture, that cures, and "permanently" seals punctures in a tyre, with
the help of the heat that is generated through contact with the road. Tyre Seal is a
proprietary formulation having unique properties which means it goes from a gel to a
liquid with centrifugal forces, and then immediately snaps back to a gel, just before
coming to rest. That's why Tyre Seal always stays dispersed on the inner tyre instead
of pooling on the bottom, which is one of the many reasons it works at high speed.
Once Tyre Seal has been installed, it conditions the tyre making the rubber supple,
thereby reducing cracking, deterioration, and porosity, and any hole caused by
puncturing objects up to 6 mm - high speed grade, 15 mm medium speed grade and 20
mm low speed grade, will be permanently sealed by Tyre Seal.
Tyre Seal does not have any of the failings that previous and many present day
products have. Apart from drying and balling up in the tyre, the biggest failings of
traditional tyre sealants in a high speed tyre, is the inability to seal small holes, but the
ability to seal a large dangerous hole or cut, because they contain large chunks of
chopped up old rubber tyres. The sealing capabilities of Tyre Seal are unparalleled by
any tyre sealant worldwide. Tyre Seal seals are positive and secure, thereby
transforming any tyre into a self-sealing tyre. Tyre Seal is capable of sealing punctures
as long as the puncturing object has not severely damaged and/or weakened the tyre's
structural integrity. Tyre Seal cannot create a secure seal in any tyre that has major
internal damage, regardless of the puncturing object's diameter. If the casing becomes

damaged or weakened to the point of being unsafe, the Tyre Seal formulation has been
designed to slowly bleed regardless of how small the wound may be, giving a controlled
deflation. Cords are instrumental in rubber recovery, and without cords a tyre will inflate
like a balloon. When cords are severely cut, the hole in the tyre will enlarge with
increased air pressure, so in a moving vehicle, Tyre Seal will assist to give this
controlled deflation as the hole shrinks with increasing air loss and reducing air
pressure.

UNDERSTANDING
Tyre Seal

Understanding Tyre Seal, and a basic guide to tyre sealants by
the Tyre Seal UK Technical officer
(This article was published in the BMW Club Magazine after a request from the editor)
With the recent popularity of Tyre Seal, and with so much lack of knowledge about our
product, I have been asked to write an article about how Tyre Seal functions inside a
high speed tyre. I will also give a little guidance as to what to look for when choosing a
puncture prevention treatment, whether for high or low speed use. Sealants in general
have been around since the early sixties. Whilst they were primarily manufactured for
the low speed markets such as construction, and agricultural use, many people
attempted to inject them into their car and motorcycle tyres resulting in problems that
were costly and sometimes dangerous. This was fueled by unscrupulous manufacturers
who saw a quick profit. You can still see these companies today advertising their
products suitable for high speed. Inexpensive sealants manufactured for low speed use
have a very basic carrier liquid, very similar to wallpaper paste that contain large
chunks of rubber that will bridge a large punctured hole. They are intended to create a
temporary plug in an off road tyre, to enable the operator to continue with the use of the
vehicle/machine until a tyre fitter is able to make a repair at the end of the day. They
cost pennies to manufacture and are sold to farmers and builders, who put them into
their tractor and JCB tyres in huge quantities. These sealants contain a high amount of
water and slop around at the bottom of the tyre, so when they are installed in a high
speed tyre (over 20mph) they are extremely hazardous, and many rust wheel rims and
corrode alloys. The worst that can happen is that large rubber chunks can log jam in a
large punctured hole that has secondary damage, and because rubber will stay slippery
when wet, the seal can fail with high speed. Even the many sealants that also contain
fibres are useless because they usually contain the wrong type of fibre that ball up in a
high speed tyre. The inexpensive and inferior polymers in these products will also
separate and dry up due to heat after 500 to 2,000 miles. With these sealants, once
separation begins, there is no recovery. Another problem that is inherent in many
sealants is their inability to disperse throughout the inner tyre. They readily flow to the
bottom of the tyre, almost like water. The fast rotating tyre forces the sealant into a
narrow band against the outermost portion of the tyre's inner surface, causing the
sealant to remain in the centre portion of the tread area, allowing no protection

elsewhere. Consequently, porosity and bead leaks continue to exist giving rise to
under-inflation. Because under inflation makes tyres run hotter and wear faster, they
become subject to punctures and road hazard damage. Hot rubber simply has less
resistance to cuts and punctures. Although an uneven road surface will cause this type
of sealant to splash around, the outwards centrifugal forces will always pull the product
back to the centre of the tread area. Any punctures that these products seal in a high
speed tyre is usually short lived with failure of the seal inevitable within a month or two
due to extreme heat and polymer shrinkage in the puncture.
So, what type of product do you need that will work effectively in a high speed tyre, and
will be 100% safe? We at Tyre Seal endeavoured to formulate a polymer gel that would
stay liquid up to speeds of 150 mph, and that would only seal a hole that was safe to
seal because it was recovering in size from a puncture because secondary damage had
not occurred to the cords, or rubber had not been lost as a result of that puncturing
object, which is usual with objects like glass and screws. We managed to formulate a
thixotropic liquid gel of over 12 polymers, all working together to withstand extremes of
heat and stress forces. Most importantly we developed a combination of special fibres
and very small, low density rubber particles that work with the polymer gel to create a
safety product of outstanding abilities. An effective sealant for high speed will be
thixotropic and in a gel form. Thixotropic describes a compound of a framework of one
kind of particle, which supports other particles within the substance, and is semi solid or
gel like. When a force is applied, the bonds between the particles in the suspension
become weaker, and the substance loses some of its structure. It then behaves more
like a liquid and the viscosity decreases as the sheer force increases, returning to the
gel state upon standing. Tyre Seal's thixotropic sealant gel is manufactured by a secret
proprietary process, not mixed like a cake recipe. Good sealants should not be ethylene
glycol based and contain a combination of fibres, particulates, pigments, adhesion
agents, rust/corrosion inhibitors, thixotropes, viscosity control agents and PH retainers,
which all come together to form an air-impervious plug in the event of a puncture. The
plug should maintain flexibility because of plasticising additives, so it flexes with the
tyre and positively remains in place sealing the puncture. Though thixotropic, such
formulas regain their fluidity due to kinetic energy from tyre revolution. Adhesion agents
should be added to hold the sealant in place after the vehicle has stopped. An effective
sealing compound remains in a thixotropic gel state and will resist flowing to the bottom
of the tyre by actually clinging to the entire inner surface, stretching as the centrifugal
forces increase, acting as a thermal conductor, transferring heat from areas of higher
temperature, to areas of lower temperature. This thixotropic state allows the compound
to stretch as sheer forces increase and revert back to its original viscosity as the sheer
forces diminish, and also prevents the centrifugal force from separating the various
polymers. Also this thixotropic state is what protects the polymer gel, allowing the
sealant to last beyond the life of the tyre. In the event of a puncture the sealant is
squeezed into the hole assisted by air pressure and capillary action, and as the
puncture rolls off the load point, leaves the fibres, particulates and polymers in the hole
to cure. Repeated rotation of the tyre under normal load deposits more fibres etc, until

the seal becomes extremely tight. Fibres, unlike rubber are very coarse surface, and
once they have keyed and intertwined together in a hole that is shrinking and has
recovered in size, they become very strong and are permanent. Our combination blend
of small rubber particles and special fibre is extremely safe, compared with chunky
rubber when they seal a hole, as they will not bridge a large gap. If cords are cut or
rubber has been lost in a puncture, then fibres will slowly bleed out of the hole giving a
controlled deflation. Our fibre blend will only stay in place where there is a good
thickness of rubber, which is why you will get a controlled deflation with a puncture to
the much thinner sidewall. It is the ability of our special blend of fibres, to distinguish
what is safe to seal, and what is not, that gave rise to our marketing slogan “Tyre Seal
is a clever thinking product”. Any legitimate sealant manufacturer shouldn't make the
claim that a high speed tyre will never go flat with its sealant installed, otherwise this
raises the question of safety.
95% of punctures are straightforward with nails cleanly penetrating between the cords
causing little damage. If a good sealant is present, then the lubrication from the sealant
will usually help expel the nail sooner rather than later, helping to avoid secondary
damage. When the nail is expelled; the puncture recovers to a tiny hole, and if a good
sealant is present within the tyre, it will positively seal the hole safely. If the puncturing
object is at a bad angle and left in for any length of time, secondary damage may occur,
so when the object is removed you should get a controlled and slow deflation. Glass
and screws are notorious for causing this type of damage by cutting the cords and
gouging tyre rubber away leaving a cavity, which is not usually seen by the naked eye.
In this instance a good reputable sealant will slowly and safely let the tyre down in a
controlled manner, and sometimes halt the air loss at about 10 to 15psi, which could
allow the driver/rider remove the vehicle from a possible dangerous location. With the
correct amount of sealant installed, tyre balance will not be upset in a well balanced
wheel. With a bad sealant fitted to an unbalanced or out of round tyre you will get an
effect of hydronomics (motion of fluids). An out of balance wheel rotates eccentrically,
causing a dislocation of mass toward the centre of gravity, but away from the geometric
centre of the wheel, producing vibration. In a well balanced tyre, thixotropic sealant gels
containing adhesion agents can dampen the occasional shudder or vibration because
they are distributed by centrifugal force to the centre of gravity, causing the geometric
centre and the centre of gravity to become aligned.
WHY IS

Tyre Seal Beneficial in a Tyre?
The majority of flats and blow-outs are a result of driver negligence. The number one
cause being excessive heat generated from under inflation. The overheated, under
inflated tyre becomes soft and can be penetrated very easily. However, under inflation
creates additional problems such as tread and ply separation, all of which is primarily
caused by porosity (natural air migration) which exists in all tyres to some degree. Tyre
Seal eliminates air migration and prevents the majority of damage created by under

inflation, thereby preventing most related blow-outs. Once Tyre Seal has been installed,
it conditions the tyre making the rubber supple, thereby helping to reduce sidewall
cracking, deterioration, and porosity.
Heat in a tyre is critical, because it helps with traction (helps the tyre stick to the road)
but excessive heat is a major problem. Heat on the outside of the tyre caused by
contact with the road eventually makes its way to the inside causing hotspots, but
because rubber is a poor conductor, very little of this heat makes its way to the rim,
which is a wheels natural heat sink. Eventually, this heat inside, builds up, causing
punctures, blowouts, excessive tyre wear, and eventual failure. This is where Tyre Seal
can help. The Tyre Seal treatment deals with this heat in two ways, it disperses then
conducts the heat to the rim, via Tyre Seal's liquid inner tyre coverage, and also due to
the fact a little of the secret liquid polymer formulation within the product vapourises
whilst the vehicle is in motion, and the heat from this vapour is transferred by
condensation to the rim with contact, where it is then passed to the outside
environment. What you have now, is a perfectly performing tyre, which has the correct
temperature on the outside to maintain traction, and cool on the inside, which will help
stop tyre failure and help extend tyre life considerably.
Tyre Seal's proprietary process does not use any glue to make a seal, so Tyre Seal is
the answer to the problem of the patch that fails due to excessive heat. On the contrary
heat is very beneficial to this process, therefore the seal cannot fail due to heat. If the
casing becomes damaged or weakened to the point of being unsafe, the Tyre Seal
formulation has been designed to slowly bleed regardless of how small the puncture
may be, giving a controlled deflation. Cords are instrumental in rubber recovery, and
without cords a tyre will blow up like a balloon. When cords are severely cut, the hole in
the tyre will enlarge with increased air pressure, so in a moving vehicle, Tyre Seal will
assist to give this controlled deflation as the hole shrinks with increasing air loss and
reducing air pressure. With Tyre Seal, and a controlled deflation, a tyre will deflate at a
rate depending on the extent of the damage, then as the tyre reaches the lower
pressures of 10 to 15 psi, a severe slow down or halt in air loss will be experienced as
Tyre Seal's unique formulation and synthetic fibres are now log jamming in a puncture
that is now shrinking in size because of these much lower air pressures. You could now
be running on a soft tyre instead of the wheel rim, which could mean the difference
between keeping control or losing control. This is possible because we do not use
chopped up rubber tyres in our formulation, we use small particle size soft rubber and 5
different sizes of specially manufactured “course surface” synthetic fibres which
interlock tightly together in the puncture.

Key Attributes

Extends tyre life
Tyre Seal maintains air pressure, retards aging within the casing, reduces heat build-up
and increase tyre life.
Protects against under-inflation
Tyre Seal has the ability to eliminate porosity, air migration and seepage, thereby
allowing the tyre to maintain proper air pressure, which in turn will prevent rolling
resistance and heat build-up, the biggest cause of high fuel consumption and tyre
failure. For retreaders this also prevents the inception of most tread separations &
ruptures.
Heat reduction
Tyre Seal assists in protecting tyres from devastating heat build-up, which is associated
with friction caused by under inflation, and/or overloading. Tyre Seal contains specific
ingredients that aid in conducting heat away from the tyre, by transmitting additional
heat to the rim (which is the tyre's natural heat sink), resulting in a cooler running tyre
for any type of equipment or vehicle, regardless of use.
Safety Factor
Tyre Seal provides safety factors that are not found in any tyre. Tyre Seal will not mask
or hide damage that has breached the integrity of the tyre. Tyre Seal is specially
formulated to allow any serious puncture (potentially dangerous) to slowly deflate in a
controlled manner. This attribute provides safety and aids in alleviating the hazards
associated with blowouts. Tyre Seal cannot create a secure seal in any tyre that has
major internal damage, regardless of the puncturing object's diameter. This is because
Tyre Seal needs rubber recovery in order to work effectively. Cords play a vital part in
rubber recovery, but in a puncture that has damaged cords Tyre Seal and air will slowly
bleed out of the tyre giving the driver a controlled deflation.
Lasts the life of the tyre
Tyre Seal's proprietary process protects the sealant against heat and provides the
ability to overcome the centrifugal force of a rotating tyre. Tyre Seal's abilities &
performance does not diminish with speed, distance or time.
Protects the entire inner surface of the tyre
Tyre Seal provides a coating that clings to more of the inner tyre, thereby providing
protection for the tyre at all times.
Positive sealing capabilities
Tyre Seal seals are positive and secure, thereby transforming any tyre into a self-
sealing tyre. Tyre Seal is capable of sealing tread area punctures caused by puncturing
objects up to 6 mm in diameter, as long as the puncturing object has not severely
damaged and/or weakened the tyre's structural integrity. Tyre Seal cannot create a
secure seal in any tyre that has major internal damage, regardless of the puncturing
object's diameter.

Water-soluble (for easy clean out)
Tyre Seal is completely water-soluble in its liquid state, and leaves no residue when
rinsed with plain water. Yet it will not dissolve within a puncture after it has cured.
Standard repairing procedures can be utilised without additional effort.
Protection against rust and corrosion
Tyre Seal contains a complete rust and corrosion inhibiting system that not only
protects steel and alloy wheels, but in a puncture, Tyre Seal's proprietary process will
also protect steel belts. Outside contaminants are prevented from leaching back into
the puncture, which would cause the steel belts to rust and the ply’s to separate.
Without Tyre Seal's protection, the contaminants would quickly destroy valuable
casings.
Cannot create a balance problem
Treating a tyre with the recommended amount of Tyre Seal does not provide for an
excessive amount of product to accumulate in the tread area, therefore the tyre is not
subjected to a mass of substance (common with many tyre sealants) that would create
an imbalance. Tyre Seal cannot create an imbalance due to the ability to evenly coat
the inner surfaces of the tyre subjected to normal centrifugal force.
If the suspension is worn beyond specified tolerance, or a tyre/rim assembly is not
balanced and/or trued, the abnormal centrifugal force generated will have enough
gravitational force to pull Tyre Seal off the vertical surfaces and collect in the problem
area thereby increasing the "existing" imbalance problem. If the problem is severe
enough the driver will feel a vibration. The vibration indicates that a problem pre-existed
in the tyre assembly or suspension prior to installing Tyre Seal.
Eliminates most flats and blowouts
The majority of flats and blowouts are a result of driver negligence. The number one
cause being excessive heat generated from under inflation. The overheated, under
inflated tyre becomes soft and can be penetrated very easily. However, under inflation
creates additional problems such as tread separations, ply separations and tread
ruptures. All of the above is primarily caused by porosity (natural air migration) which
exists in all tyres to some degree.
Tyre Seal eliminates air migration and prevents the majority of damage created by
under inflation, thereby preventing most related blowouts. The sealing capabilities of
Tyre Seal are unparalleled by any tyre sealant, worldwide.
Will not void tyre warranty
Tyre manufacturers state that tyre sealants do not void their warranties unless it can be
proved that the additive caused a problem to the tyre structure. Tyre Seal's polymer
composition is completely compatible with all tyre components.
Compatible with all retread methods
Tyre Seal conditions the casing and retards aging. Plus, the ability to be thoroughly
cleaned out of the tyre assures no hindrance for inspection. The product is non-toxic,
non-hazardous, non-flammable, does not present a disposal problem and has no
compatibility problems.

HOW DOES

Tyre Seal Function Inside a Tyre?
It is very important that you understand two aspects regarding the performance
characteristics of a tyre, in order to fully comprehend how Tyre Seal Tyre Life
Extender/Conditioner actually functions, along with and as part of the tyre
What is rubber recovery?
Rubber recovery within a tyre, is very important in conjunction with Tyre Seal. When a
tyre is punctured, the rubber is forced open by the penetrating object. The puncture is
actually much smaller than the puncturing object.
Rubber has memory and it will recover to its original shape after being subjected to
adverse conditions or stress factors. When the penetrating object is removed, the
rubber recovers and the puncture closes (a tyre that is old, worn out and/or dry rotted
will have little or no rubber recovery).
A penetrating object left in a tyre for any extended period of time causes the rubber to
temporarily lose its ability to recover. After removing the puncturing object, it is
recommended to immediately flex the tyre to reactivate the rubber's memory. As the
puncture closes, Tyre Seal is held in place by the strength and integrity of the tyre and
will then create a positive secure seal.
What is tyre flexing?
Tyres are constantly flexing when a vehicle is driven. The weight of the vehicle, the
irregular surface of the road, and the turning of the tyres create a substantial amount of
flexing.
Once the puncturing object is removed, it is important for the Tyre Seal seal to be
forced into and through a puncture. Once this is accomplished the seal cures and
becomes a positive secure seal.
Manual tyre flexing (off the vehicle) can be accomplished by removing the puncturing
object and then striking the tyre several times with a mallet around the puncture area
and/or bouncing the tyre against the ground. This method creates a temporary seal that
will become positive once the tyre is installed onto the vehicle and driven approximately
3 to 5 miles.
Is it necessary for you to understand tyre construction?
NO! There are many variables in tyre construction. In order for a tyre sealant to
function properly the tyre sealant manufacturer must have knowledge of the sealant
and tyre compatibility, plus have the knowledge and ability to perform exhaustive
testing that will assure that the sealant new or used is compatible.
Compatibility and chemical composition is important when a sealant is new in order to
meet Health and Safety requirements, but most importantly is what happens to the tyre
sealant formulation after it has been run a few thousand miles, and exposed to the
normal heat in a tyre and the shear and stress that results from the centrifugal force
generated in a rolling tyre.

Most generic tyre sealants can become toxic and/or an environmental hazard. Heat
build-up is an important factor and the primary reason average generic tyre sealants fail
to perform as claimed.
How does Tyre Seal produce a positive/secure seal?
Once the initial driving/usage period has been attained (3 to 5 miles), Tyre Seal will be
distributed over the crown area and after 1500+ miles throughout more of the inner
surface of the tyre. Tyre Seal makes a very thin coating which has the ability to remain
suspended on to the tyre.
It's Tyre Seal's proprietary process that prevents the formulation from separating and/or
migrating to the tread area.
Tyre Seal is a liquid coating that conditions the inner surface and eliminates porosity
and bead leaks as minute amounts of air attempt to escape. Tyre Seal continuously
stands on guard to protect tyres against air loss from punctures for the tyre's legal tread
life.
When a tyre is punctured, Tyre Seal is forced against and around the puncturing object
by the inner air pressure, thereby preventing air from escaping.
If the puncturing object is thrown out of the tyre by centrifugal force or is pulled out, the
inside air forces Tyre Seal into the puncture and immediately stops air loss. Special
fibres entwine, forming a seal, then as the rubber recovers (see rubber recovery), aided
by the flexing of the rotating tyre, the inner air pressure forces the seal well into and
through the puncture.
Once Tyre Seal is exposed to outside air, a unique curing process begins. The seal
extends well into and through the puncture and once cured provides a seal that is
impervious to water.
The cured seal, is then transposed into a positive rubberised seal, thereby protecting
the inner casing and steel belts by preventing outside contaminants from leaching into
the wound.
Will Tyre Seal cure or harden inside of the tyre?
People often ask "If Tyre Seal cures from exposure to outside air, then why does it not
cure by the air inside of the tyre?"
As the vehicle is driven and the temperature of the tyre increases, a portion of Tyre
Seal's liquid base evaporates within the tyre's inner air cavity, as the tyre cools, the
vaporised liquid condensates back into the formula. The inside air actually becomes
part of the Tyre Seal system. The sealed air chamber prevents outside air from entering
or inside air from escaping. Constant air pressure resetting is not required. Tyres and
air pressure should be inspected during routine maintenance.
Why does Tyre Seal not cause a balance problem?
It is extremely important to understand how Tyre Seal's proprietary process, not found
in any other tyre sealant, prevents any balance issues prevalent in the majority of other
sealants.
Tyre Seal clings to the inner surface of a properly balanced and true (round) tyre. The
centrifugal force that is created within a high-speed tyre actually stretches Tyre Seal

much like a rubber band; however, it will not pull Tyre Seal off the inner surface of a
properly balanced tyre.
A sufficiently out of round and/or out of balance tyre can create enough adverse force
that could pull the coating of Tyre Seal from the tyre's inner sidewalls. If a tyre requires
an excessive amount of weights to be installed to achieve a good reading on the
balancer, the tyre should be inspected for defects and corrected prior to installing Tyre
Seal. Tyre Seal cannot correct an existing problem and may aggravate an adverse
situation.
The proper amount of Tyre Seal for high speed vehicles has been scientifically
calculated to provide the proper coating to the inner surface of the tyre, allowing for
absorption into the casing, yet still maintain a reserve.
The reserve (approximately 20% of the installed amount) is extra Tyre Seal that will
shift/move. Only the reserve will settle to the bottom of the tyre when the vehicle stops.
The reserve constantly redistributes as the tyre rotates, thereby continually providing
an even coating. Each time a puncture occurs, a small amount of reserve is used.
Ethylene Glycol is a Toxic

Antifreeze -

so it is not in Tyre Seal

Tyre Seal does not contain Ethylene Glycol. It took us years to find a non glycol anti
freeze which was suitable for use in a tyre sealant and that was non toxic. Ethylene
Glycol is one of the most toxic substances used in tyre sealants worldwide because 2
teaspoons of Ethylene Glycol can kill an adult within 2 days. Our biggest concern was
for the regular users of our tyre sealant who could be poisoned by absorption through
the skin, eventually getting a build up of kidney stones (calcium oxalate crystals).
Because the body cannot remove these calcium oxalate crystals in the kidneys, a build
up over time could be fatal. Our other concern was for the passengers of a car
breathing in the Ethylene Glycol vapours from a very hot severely damaged flat tyre
placed in the boot. Also because children and pets could have access to tyre sealants
that contain Ethylene Glycol and because we have a duty of care policy we considered
it irresponsible to use this in our products. We have always supplied a glycol free
sealant which is 100% non toxic and 95% organic.
Toxicity
Ethylene Glycol poisoning can be divided into three stages. Stage one includes central
nervous system (CNS) disturbances and gastrointestinal symptoms. Stage two includes
signs of cardiovascular, pulmonary, and metabolic irregularities and stage three
includes renal failure brought on by the precipitation of calcium oxalate crystals in renal
tubules and from the direct toxic action of oxalic and glycolic acids upon the kidneys.
Safety standards in the world are not as advanced as the UK and the majority of these
E/G sealants are coming in from North America.

The major danger from Ethylene Glycol is ingestion. Due to its sweet taste, children
and animals will sometimes consume large quantities of it if given access to antifreeze.
Ethylene glycol poisoning is a medical emergency and in all cases a poison control
centre should be contacted or medical attention should be sought. It is highly toxic with
an estimated LD100 in humans of approximately 1.4 ml/kg. However, as little as 30
milliliters (2 tablespoons) can be lethal to adult. For Hazardous Substance Fact
Sheet, CLICK HERE.
Symptoms
Symptoms of Ethylene Glycol poisoning usually follow a three-step progression,
although poisoned individuals will not always develop each stage. Stage one consists
of neurological symptoms including victims appearing to be intoxicated, exhibiting
symptoms such as dizziness, headaches, slurred speech, and confusion. Over time, the
body metabolises Ethylene Glycol into other toxins, first to glycolaldehyde, which is
then oxidized to glycolic acid, glyoxylic acid, and finally oxalic acid. Stage 2 is a result
of accumulation of these metabolites and consists of tachycardia, hypertension,
hyperventilation, and metabolic acidosis. Stage 3 of ethylene glycol poisoning is the
result of kidney injury, leading to acute kidney failure. Oxalic acid reacts with calcium
and forms calcium oxalate crystals in the kidney. An estimated 80% of kidney stones
are calcium oxalate.
Ethylene Glycol is a good anti freeze additive in a tyre sealant but that might have been
OK throughout the 1960s but we think that is unacceptable today. We at Tyre Seal
knowing that children/pets can have access to a tyre sealant and that unaware and
untidy installers will allow the sealant soak through their skin, we decided to invest in
years of laboratory research to find a non toxic alternative that would complement the
sealing properties of our sealant. During our research and development we discovered
that everything available came with their own problems when added into a tyre sealant
and this was probably why no manufacturer in this industry bothered to invest the huge
amounts in time and money needed to find the perfect non toxic antifreeze suitable for
a product going to the general public. We did it, but it was exhaustive. We are now
satisfied in the knowledge that we have a safety product that will not be harmful
to the unsuspecting.
