How Ultraseal Works

Ultraseal Tyre Sealant Description

Once Ultraseal has been installed, it will lay dormant at the bottom of the tyre until the vehicle is driven. Once driven a minimum of three to five miles, Ultraseal disperses throughout the inner air cavity and forms a coating on the entire inner surface of the tyre/wheel. The flexing of the tyre and the normal heat build-up will allow Ultraseal to seek out and eliminate common air loss problems (referred to as air migration and bead leaks). Ultraseal then transforms the tyre/wheel into a sealed air chamber, capable of maintaining proper air pressure. Thereafter, Ultraseal conditions the rubber in order to retard dry rot and hardening of the casing. One treatment will provide additional longevity and cooler running tyres.

The advanced technological sealing capabilities of Ultraseal stand on guard, to seal punctures as they occur.

When a tyre is punctured, Ultraseal 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. Any escaping air will siphon Ultraseal into the wound. The fibers begin to entwine and create a clot to prevent any additional air from escaping.

As the rubber recovers, the wound closes and the strength of the tyre holds the repair in place. The specialized polymers and fibres form a clot, producing an airtight repair. The small amount of Ultraseal that penetrates through the wound, past the belts and out through the tread area is referred to as a repair/clot. Once exposed to the atmosphere, the repair/clot begins a systematic chemical cure (another proprietary attribute from the Ultraseal R&D Team).

As the repair/clot cures, it makes a permanent repair that is impervious to water, which totally protects the belts and inner casing from outside contaminants and corrosion.

Ultraseal s formulation contains Thixogel , one of our closely guarded secrets that allows Ultraseal to withstand heat and the shear forces created within a rotating tyre. The thixotropic emulsion stretches and recovers under mild to severe exposure of the adverse forces and continuously clings to the inner surface of the tyre/wheel. The ability to evenly coat the inner surface against adverse conditions and centrifugal force is the reason that Ultraseal Tyre Life Extender/sealer will not adversely affect a balanced tyre/wheel and will not lose the ability to provide protectionfor the tread life of the tyre. Ultraseal’s operating temperatures under normal conditions range from -40°F to +302°F.

Ultraseal Pump

Highway Performance

1. HiPerformance grade - is formulated for any vehicle with pneumatic tyres, tube or tubeless, high or low air pressure and used regularly in highway speed. This formula is guerenteed to seal wounds caused by puncturing objects up to 5mm in diameter in the tread. Ultraseal is designed to bleed and slowly release air pressure, if the wound has damaged the inner structure and the tyre has been rendered unsafe. Ultraseal will not hide or mask a dangerous wound regardless of how small it may be. 

Commercial/Industrial

Commercial/Industrial grade - is formulated for any vehicle with pneumatic tyres, tube or tubeless, high or low air pressure and used in highway speed vehicles or slow off road equipment tyres. This formula is guerenteed to will seal wounds caused by puncturing objects up to 6mm in diameter in the tread. Ultraseal is designed to bleed and slowly release air pressure, if the wound has damaged the inner structure and the tyre has been rendered unsafe. Ultraseal will not hide or mask a dangerous wound regardless of how small it may be. 

 

Extra Heavy Duty (XHD)

3. Heavy Duty ’XHD’ grade - is formulated for Military combat vehicles, armoured vehicles and off road equipment. Used in combat vehicle tyres where bullet wounds would prevent any vehicle from completing its mission, Ultraseal is guerenteed to seal large wounds up to 12mm in the tread, allowing the vehicle to remain mobile. Once again, Ultraseal provides that extra reliability and very important uptime on mining and construction equipment, where downtime is extremely costly. XHD grade is not designed for regular passenger vehicles. It will seal wounds caused by puncturing objects up to 12mm in diameter.

Coating and Conditioning

After installation, and once the vehicle has been driven approximately 5-7km (it is not necessary to do this immediately), Ultraseal coats and clings to the tyre’s entire inner air cavity, conditioning the inner surface, eliminating porosity and bead leaks. Thixogel prevents Ultraseal from migrating to the tread area at high speeds.

AIR MIGRATION is the multitude of porous passage ways that allow air to penetrate and migrate through the tyre’s inner structure. It is next to impossible to produce a new or retreaded tyre without some air migration existing. As the vehicle is driven, tyre temperature increases, the air inside the tyre expands and air bubbles are forced into the porous passage ways. Once the air bubbles migrate into the inner structure they will continue to expand from heat. If the migrating air cannot escape through the tyre’s various plies and into the atmosphere, it will eventually cause tread separation and/or a bubble on the sidewall. If the migrating air does escape the tyre is left underinflated, either way, premature tyre failure is inevitable.

Underinflation is the #1 cause of blowouts.


Permanent Repair (safe secure repair)

When a tyre is punctured, Ultraseal 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 Ultraseal into the wound and immediately stops air loss. Special fibres entwine, forming a clot, then as the rubber recovers (see rubber recovery), aided by the flexing as the tyre rotates, the inner air pressure will force the repair/clot well into and through the wound. Once Ultraseal is exposed to the outside air, a chemical curing process begins. The cured repair/clot extends well into the wound, thus providing a repair that is imperviousto water (rain, snow, mud, etc.). As this repair/clot cures, it is transposed into a permanent rubberized seal, protecting the inner casing and steel belts against contaminants entering the wound.


Rubber recovery?

Rubber recovery within a tyre, is very important in conjunction with Ultraseal. When a tyre is punctured, the rubber is forced open by the penetrating object. The wound is actually much smaller than the puncturing object. Rubber has memory and it will recover to its previous shape after being subjected to adverse conditions or stress factors.

When the penetrating object is removed, the rubber recovers and the wound 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 wound closes, Ultraseal will be held in place and will create a permanent repair/clot.


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. It is important for the Ultraseal repair/clot to be forced into and through a wound. Once this is accomplished the repair/clot cures and becomes a permanent seal.

Manual tyre flexing can be accomplished by striking the tyre repeatedly with a mallet around the wound area and/ or bouncing the tyre against the ground. This method creates a temporary repair that will become permanent once the tyre is installed onto the vehicle and is returned to service or driven approximately 3 to 5 miles.

Ultraseal will not cure or harden in the inside of the tyre

People often ask "If Ultraseal cures from exposure to outside air, then why doesn’t it cure by the air inside of the tyre?" As the vehicle is driven and the temperature of the tyre increases, a portion of the liquid base evaporates within the tyre’s inner air cavity, as the tyre cools, the liquid 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 resettings are not required. Tyres and air pressure should be inspected during routine Preventative Maintenance (PM) program.


Installation Overview

Installing Ultraseal is quite easily accomplished using specially designed high-pressure pumps, valve core removal tools and attachments. In the vast majority of cases, Ultraseal is simply pumped through a tyre’s valve after the installer has removed the valve core. Removal is quick and easy using patented valve core remover tools. An average automobile tyre can be treated in less than two minutes, with typical truck and heavy equipment tyres taking three to five minutes. Times will vary depending on a vehicle’s wheel configuration and your familiarity with Ultraseal tools and techniques.

Treating mounted tyres that have not yet been installed on vehicles can cut installation times by as much as half due to easy access and proximity. This is a common practice in fleet operations. It is not necessary to immediately install treated tyres; Ultraseal will lie dormant at the bottom of a tyre until rotated. This will reduce porosity and bead leaks, insuring tyres retain air pressure and are fully inflated when ready to be placed into service
