ABSTRACT:
A new tire sealant and inflator composition is described which utilizes a sealant having superior performance, presented in a water-based carrier, and with an inflator composition consisting of mainly dimethyl ether, modified by trichloroethylene and nitrogen gas. The composition comprises a terpolymeric latex sealant emulsion, prevented from coagulating or vulcanizing in the dispenser by the addition of additives, and made more potent by the inclusion of certain wood flours having selected particle size distributions. Other ingredients, such as propylene glycol, a surfactant, triethanolamine and ammonia, confer special attributes; for example, softening the wood flour particles and keeping them dispersed in the aerosol can, while causing them to pack down into a sealing matrix once added to a tire having a puncture. Since no environmentally acceptable gases exist that can be used in aerosol sealant/inflator products, a combination has been selected which is far less intrinsically flammable than the very commonly used propane/butane (LP-Gas) propellants.
