Abstract
A tire puncture sealant containing water in an amount of from about 6% to about 64% by weight; ethylene glycol in an amount of from about 36% to about 94%; styrene butadiene latex in an amount of about 3%; polyethylene powder and ground rubber in an amount from about 3% to about 6%; a minor effective amounts of an alkali metal carbonate, a cellulosic thickener, an alkali metal nitrite and a corrosion inhibitor. The polyethylene powder and ground rubber are preferably surface-activated and include various particle sizes.
Claims27
A sealant composition comprising a particulate, surface-activated, polymeric component dispersed in a fluid medium comprising water, a freeze preventative selected from alkyl polyols, and latex;
- wherein the particulate polymeric component is selected from the group consisting of particles of rubber and polyethylene, said particles having a particle size ranging from about 35 to about 2000 microns that have been contacted with chlorine gas and are present in an amount ranging from about 3% to about 6% by weight of the composition.
A tire puncture sealant comprising:
- water in an amount of from about 6% to about 64% by weight of said tire puncture sealant;
- ethylene glycol in an amount of from about 36% to about 94% by weight of said tire puncture sealant;
- styrene butadiene latex fluid in an amount at least about 3% by weight of the tire puncture sealant;
- chlorine contacted polyethylene powder in an amount of from about 0.1% to about 5% by weight of said tire puncture sealant;
- chlorine contacted ground rubber in an amount of from about 0.1% to about 5% by weight of said tire puncture sealant;
- about 0.5% by weight of an alkali metal carbonate;
- a cellulosic thickener in an amount of from about 0.1% to about 5% by weight of said tire puncture sealant;
- an alkali metal nitrite in an amount of about 0.5% by weight of said tire puncture sealant;
- and
- a corrosion inhibitor in an amount of from about 0.1% to about 5% by weight of said tire puncture sealant.
