What types of equipment can Air-Seal Products be installed in?

Our sealants can be used in any pneumatic tyre and are normally used for puncture prevention in a wide range of on and off road equipment; for example, heavy earth moving and other large and medium sized plant used for motorway and major construction projects, landfill and transfer station sites. The tyres of loading Shovels, telehandlers, backhoe's, dumper trucks of all sizes, roll on and roll off's, skidsteers, tractors, lorries large and small right down to the essential wheelbarrow. All of these examples and many more have all been successfully treated with the recommended grade of sealant.

How will I benefit if I install your sealants?

Our sealants can stop up to 95% of punctures in the tread area from the usual causes. Slow air leaks are eliminated which means longer tyre life and lower fuel consumption.

Most blowouts are caused by excessive heat build up in the tyre almost always caused by under inflation. Slow air leaks increase this risk but are prevented if our tyre sealants are used.

Equally important is the fact that our tyre sealants are homogeneous and will not separate at any speed or when the vehicle is stationary.

What are the applications for the range of sealants supplied?

Air-Seal Products have three different grade formulations. Each grade is designed to fit a specific need. The following table gives a brief outline of the grades and applications.

GRADE APPLICATIONS EFFECTIVENESS
Armor-Seal Usually for off road conditions which are difficult or hazardous for heavy plant with tyres of 18 ply upwards. Punctures up to 30mm (1¼ inches) and slow air leaks.
Heavy Duty Used for on/off road vehicles working in demanding locations. Punctures up to 15mm (5/8 of an inch) and slow air leaks.
Recreational Trailers, grounds care equipment, sports and leisure activities as well as private use. As for Heavy Duty. Supplied only in 950ml bottles.

 

For road going vehicles it is essential that the wheels are correctly balanced prior to installation and the tyre re-inflated to recommended pressures.

Will conventional tyre repair procedures be prevented?

No. If the tyre is damaged beyond the ability of the sealant to plug the hole, the tyre can be 'patched' or 'booted'. The tyre repairer simply needs to wipe the area around the hole clean and then wipe it with a water soaked rag. The tyre can then be repaired using normal methods. It is not necessary to remove the remaining sealant but if there has been a significant loss, it should be replaced either from a 20 Litre pail or a 950ml bottle. Care is necessary to avoid the contamination of the sealant during the repair.

Are these sealants effective in both tubeless and tubed tyres?

Yes in both types. It is up to 95% effective in tubeless and 75% in tubed tyres.

Can Air-Seal sealants be used to repair a punctured tyre?

Yes. It is possible but their main purpose is to stop punctures. Not every puncture can be prevented but before treating the tyre it will be necessary to have a foot pump or a source of compressed air available to re-inflate the tyre to its correct pressure. When installation is completed, the wheel must be rotated immediately by driving the vehicle a short distance to allow the plug to be formed to seal the hole.

Is it necessary to fully deflate the tyre before installing the sealant?

No. The 20 Litre pails use specially designed pumps which can install the product in partially inflated tyres. However with bottle applications deflating the tyre is necessary.

Is an Air Seal sealant plug permanent?

Yes. A permanent repair is achieved by the interlocking fibres and fillers creating a flexible plug in the tyre wound.

How long will Air-Seal sealants last?

For the legal life of the tyre and beyond. These sealants will not react with the rubber and other constituent materials in the tyre. Most importantly, the components of the sealant will not separate in use. The sealant range carries no expiration date either so in larger applications, can be re-used.

Are Air-Seal products expensive?

We are confident that our range of sealants have the best technology and cost benefits which give excellent value for money for the tyres of every vehicle which is treated. One application in to the tyre, will typically cost no more than one puncture repair.

How are these sealants installed?

The installation of our range of tyre sealants can be completed in 3 easy steps:

  1. Remove valve core and deflate tyre (if necessary) to around 40 psi.
  2. Attach installation pump and open the hose end valve. 
  3. Pump in required dosage amount based on the tyre size, re-install the core of the valve and re-inflate the tyre to the manufacturer's specifications. 
Please note: For bottle applications you will need to deflate the tyre completely.

 

Is the amount of Air-Seal tyre sealant installed in the tyre important?

Yes. It is most important that the recommendation quantities are installed in the tyre to be treated. The recommended application rates will ensure the maximum benefit and give protection for the legal life of the tyre.

When I get a puncture, should I let the vehicle stand while the plug cures?

No. In fact the tyre should be used at once. The more the vehicle is used, the better the plug will be. If you remove a puncturing object, we recommend that you immediately use the vehicle. Rotation of the tyres is important in the sealing process. The plug is mechanically formed; it is not a chemical reaction. The plug is formed within seconds and the puncture is sealed with almost no air loss. With Air-Seal tyre sealant you may not even know you have had a puncture.

Do Air-Seal sealants have a shelf life?

These sealants have an indefinite life span. After installing the product, if any remains it is recommended that the lid of the pail is replaced to avoid the possibility that some 'skinning' may form. Should this happen, it will easily be stirred in ready for the next installation.

Will Air-Seal sealants corrode or rust my wheels?

No. There will be no corrosion or rust. Aluminium rims are also protected.

Could these sealants corrode the steel belting in my tyres?

No. Air-Seal sealants provide three way protection. Firstly, corrosion inhibitors in the formulations will protect the steel belting. Second, the plug formed by the sealant will keep water from penetrating through the hole in the tyre into the belting. Third by keeping the tyre inflated, the normal pressure is maintained which in turn prevents inward water seepage.

Could the sealants damage the rubber or other materials used in the wheel/tyre assembly?

No. There is no reaction between the sealants and these materials.

Do Air-Seal products require stirring before installation?

No. These sealants are supplied ready for use and stirring is not needed as the products will not separate.

Are Air-Seal sealants water washable?

All our range of sealants are water washable and do not stick to the tyre rims and beads. When necessary it can be easily flushed out of the tyre with cold water.

Are Air-Seal sealants a hazard to the environment?

Our Heavy Duty sealants contain propylene glycol which is also used in anti freeze products which are not regarded as hazardous. These formulations do not contain either caustic or acidic materials. If there is a spillage, clean up using absorbent materials and wash down the area with water. Armor-Seal will follow this example later in 2017. C.O.S.H.H. Substance Report for these sealants are available.

Is exposure of these sealants hazardous to humans?

These sealants are neither acidic nor caustic and contain no volatile organic compounds. Propylene glycol is safe to handle but we recommend the use of safety glasses or a face shield and gloves during installation. Wash with soap and water after handling the product. The product must not be swallowed: a large quantity could cause illness or even death. C.O.S.H.H. Substance Reports are available.

Will these sealants freeze in cold weather?

The freeze point for all Air-Seal sealant is below -35ºC.
