UN PROCEDIMIENTO PARA ADHERIR UNA PRIMERA PIEZA DE PLASTICO A UNA SEGUNDA PIEZA DE PLASTICO

摘要

A bonded plastic structure which comprises plastic parts of reaction injection molded polyurethane or reaction injection molded nylon coated with a primer coat and bonded together with a thermoplastic block copolymer. The primer coat comprises a moisture-curable polyisocyanate. The block copolymer comprises from 40 to 80 weight percent crystalline polyester or polyamide segments and 20 to 60 weight percent amorphous polyamide or polyether segments and has a crystalline melting point of at least 155 DEG C. The bonded structure is adapted to survive the hot environment of paint curing ovens.
