Abstract
A composite extrusion for an automotive seal strip is formed of an extruded body, and a veneer extruded onto the body. The extruded body is composed of ethylene-propylene diene rubber compound. The veneer is composed of a polymer blend that includes the reaction product of an acrylate polymer and a glycidyl acrylate polymer. The reaction of the acrylate polymer and the glycidyl acrylate polymer improves adhesion and also provides a barrier to inhibit migration of vulcanizing agents from the ethylene-propylene diene rubber body into the veneer that would otherwise cause discoloration during use.
