Abstract
It is object of the present invention to provide a method by which a variable property component, such as two-color parts, having the interior covered with a thin film of the surface area is molded from polyurethanes by RIM, eliminating the need for separately applying a mold release agent or colorants to the cavity surface. Greater latitude in design due to varying physical characteristics is provided.
