Abstract
A process of applying an adhesive to an elastomer includes the application to the elastomer of a two part adhesive formulation. The adhesive having a Part A including at least a polyol, an adhesion promoter, a chain extender, a catalyst, a water scavenger; and a Part B comprising: polyurethane prepolymer, adhesion promoter and a plasticizer. The two part adhesive formulation is cured to form the adhesive. In contrast to the prior art, no priming or surface activation is required to obtain a high strength bond to the elastomer. The resulting article of an elastomer with the resultant adhesive is sufficiently strong to result in surface peel off of the elastomer. A kit is provided for the repair of an elastomer without resort to priming the elastomer.
