Poly 74-20 Liquid Rubber is a two-part, liquid polyurethane system that cures (RTV) to a yellow, Shore A20 rubber. This is the softest rubber in the Poly 74-Series line of polyurethane mold rubbers. Poly 74-20 is a pourable rubber, but it can be easily thickened with PolyFiber II Thickener for brush-on application.
Poly 74-20 liquid polyurethane rubber is designed for making flexible, high-performance, high-strength molds that are particularly well-suited for
