ABSTRACT:
Blends of silicone surfactants substantially free of isocyanate reactivity and certain polysiloxane compounds having pendant organic chains which have at least one isocyanate reactive functional group are useful as internal mold release agents. These blends form stable dispersions in liquid polyisocyanates for use in reaction injection molding techniques.
