Composite laminate structures for automotive trim components, and methods and tie layers employed to make the same

摘要

Laminates include a thermoplastic substrate layer, a clear coat layer, and a tie layer. The tie layer most preferably includes an adhesive-enhancing effective amount of a thermoplastic reactive terpolymer of ethylene-methyl acrylate-glycidyl methacrylate (E-MA-GMA) which adhesively bonds the substrate and clear coat layers one to another. Most preferably, the tie layer is a blend of E-MA-GMA and a tackifier (e.g., a C6-C8 cycloaliphatic hydrocarbon resin). The laminate may be employed to manufacture a variety of shaped articles, most preferably automotive trim components.
