Abstract
A rubber composition which in the cured state shows improved adhesion to substrate through hydroxyl-reactive adhesives such as polyurethane comprises a first elastomer such as EPDM which shows generally poor adhesion, a minor proportion of a halogenated elastomer, phenol resin, a curative system for covulcanizing the elastomer, and an aminic substance which catalyses reaction between the resin and isocyanate containing adhesives.
