Abstract
A coating blend composition is a physical admixture of an adhesion promoter resin and a coating material resin. The blend can be cured by one or more curing agents existing within either the adhesion promoter resin, the coating material resin, or both. The utilization of such a blend eliminates the need for priming a substrate such as a rubber, or a thermoplastic or a thermoset polyolefin. The adhesion promoter resin is a urethane composition containing a blocked polyurethane prepolymer whereas the coating material resin can generally be any compound which has a functional or cosmetic purpose such as a different type of blocked polyurethane, and is generally utilized in a major amount. A particular application of the coating blend compositions of the present invention is to a glass run channel made from, for example, EPDM, as in an automotive door.
