METHOD OF COATING PLASTIC MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a coating method, by which a heat hardening process of a primer coating film is omitted and a multiple film is sufficiently hardened even when the film thickness of a clear film is made thin in the formation of the multiple coating film formed by applying a primer, a color base coating material and a clear coating material on a polyolefin molding. SOLUTION: The method of coating the polyolefin molding is performed by applying successively an one-pack type primer (A) containing a chlorinated polyolefin, a polyester polyol and an aliphatic and/or alicyclic block polyisocyante, an one-pack type base coating material (B) containing a polyester polyol and an aliphatic and/or alicyclic block polyisocyanate and a two-pack type acrylic resin clear coating material (C) containing a combination of a hydroxide-containing acrylic resin and a polyisocyanate on the polyolefin molding.
