ABSTRACT:
The bond strength of composite articles of rubber adhered to ferrous metal substrates through an adhesive is substantially improved at ambient and elevated temperatures by using as the adhesive an interpolymer comprising a conjugated diene and a heterocyclic nitrogen base and containing about 5-180 parts of silica filler per 100 parts by weight of interpolymer. Further improvement is achieved by using a rubber containing about 0.025 to about 1.0 parts by weight of a cobalt compound, calculated as cobalt metal, per 100 parts of rubber.
