ABSTRACT:
A reaction injection molding process for producing a coated polyurethane part in which a liquid mixture of polyurethane reactants is injected into a mold where it is reacted and molded into a shaped part at elevated temperatures. The surface of the mold is coated, prior to molding, with a coating composition containing a polyurethane catalyst. The catalyst acts to bond the coating composition to the molded part so that the shaped part upon removal from the mold contains a firmly adherent coating of the coating composition.
