摘要
A repaired elastomer article (200) has a hollow (210) in a non-reinforced portion of the article (200). A cured preformed plug (225) resides within the hollow (210) and is adhered to the article (200) through an amine curable polymer or prepolymer (240). The amine polymer or prepolymer (240) is curable at ambient temperature. The preformed plug (225) is made of a material which is compatible with the elastomer of the article. The preformed plug material desirably has a lower modulus than the elastomer of the article (200) and hence exhibits good physical properties such as enhanced longevity of the repair, good wear and the like. Since the amine curable polymer or prepolymer cures at ambient temperatures, the repair of the elastomer article (200) can occur in situ. The invention is especially useful in the repair of tires.
