Abstract:
1. A method for forming a composite extrusion for a trim seal strip comprising: extruding a body composed of ethylene-propylene diene rubber compound and having a surface; extruding a layer onto said surface composed of a polymer blend comprising an acrylate polymer and a glycidyl acrylate polymer; and curing said layer to form a veneer bonded to the body, wherein said curing includes reacting said acrylate polymer and said glycidyl acrylate polymer and the acrylate polymer and the glycidyl acrylate polymer form a reaction product having an affinity for ethylene-propylene diene rubber compound and forming an interfacial barrier effective to inhibit migration of polar agents from said body into said veneer.
