ABSTRACT:
The addition of a small amount of a halogen compound, e.g. chloroethyl phosphate, in a process producing elastomeric polyurethane RIM parts using tertiary amines as the chief catalyst component results in scavenging the residual amines after the part has been cured by annealing. The parts from such a process can be coated with a wide variety of enamels having a high solids content and completely cured to result in a higher degree of adhesive between the coating and the part's surface than those parts from a process without the use of such a halogen.
