Tire repair by patch only method.

摘要

A repaired elastomer article having a cut or crack entirely therethrough. An interior cavity is located in the vicinity of the cut or crack and has a filler therein. A treating agent is located about the cut portion on the inner surface of the article and an amine curable polymer or prepolymer resides over said treating agent. A cured elastomeric patch resides over said amine curable polymer or prepolymer. Since the amine curable polymer or prepolymer cures at ambient temperatures, the repair of the elastomer article can occur in situ. The invention is especially useful in the repair of tires.
