Abstract
A novel tire sealant and inflator composition comprising a resin, a latex sealant, alkylene glycol, fibers, an alkanolamine, a foaming agent, and water. The composition is packaged in aerosol cans with a chlorofluorocarbon propellant/inflator and used to seal and inflate punctured tires. The composition is applied to the punctured tire through the valve stem, and acts to seal the puncture and inflate the tire sufficiently to support the weight of the car.
