Abstract
For securing together elastomeric substrates in surface-to-surface contact an adhesive for interposing between the substrates includes elastomer, a prepolymer or a polymerizable monomer, and a graft initiator. Molecular grafting occurs between the elastomer of the adhesive and the elastomer of both of the substrates, and after curing the layer of adhesive forms an integral assembly with the substrates, to result in a bonding strength which is much higher than is obtainable with known surface adhesives. The adhesive is of particular utility in bonding new tread bands to tire casings in the re-capping of used automobile tires.
