Abstract

PURPOSE: To improve dimensional stability of coated synthetic resin molded product, by molding crystalline synthetic resin and heat treating the molded product at a temp. above the subsequent baking temp., followed by coating and baking.
CONSTITUTION: A molded product consisting mainly of crystalline synthetic resin is heat treated at a temp. above the baking temp. prior to coating and baking. In case with polypropylene, for example, the molded product is heat treated at 90W110°C which is higher than baking temp. and at which shrinkage factor of the resin is stabilized quickly, followed by primer coating, baking, top-coating and baking. The heat-treated molded product does not shrink even when subjected to subsequent low temp. baking, for recrystallization of the resin has been completed and the molded product has a consistent shrinkage factor by the above treament.
