Tire Sealant and Inflator

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 resin component of the novel tire sealant composition is present in an amount from about 20 to 40 wt.%. In a preferred embodiment, the resin is present in an amount from 25-30 wt.%, and most preferably at 27 wt.%.

The latex sealant component is also present in an amount from about 20-40 wt.%. In a preferred embodiment, the latex sealant is present at 25-30 wt.%, and in the most preferred embodiment, at 27 wt.%.
An alkylene glycol is present in the sealant composition in an amount from 2-20 wt.%. In a preferred embodiment, the alkylene glycol is present from 5-10%, and most preferably at 7.5%.

The fibers are present in the composition in an amount from about 0.1 to 1.5 wt.%, although in a preferred embodiment they are present in an amount of from 1-5 wt.%, and most preferably 2%. The fibers can be any suitable fiber which promotes clotting when the composition is applied to a puncture. Suitable fibers include, but are not limited to, inorganic fibers, such as asbestos and fiberglass, and organic fibers, such as cellulose, polypropylene, and similar natural or synthetic polymeric fibers.

The alkanolamine component is present in an amount from about 0.1-15 wt.%. In the preferred embodiments, the alkanolamine is present in an amount of from 1-4%, and most preferably in an amount of 1.8%. The alkanolamine is preferably an alkanolamine of up to 6 carbon atoms in which the amine may contain one or two akyl substituents of up to 5 carbon atoms.

The foaming agent is present in an amount from about 0.1-10 wt.%, preferably from 0.5-2 wt.%, and most preferably at 1 wt.%. The foaming agents of this invention are fatty acid derivatives having from 10-25 carbon atoms.
