FormRub 50 Liquid Rubber


FormRub 50 Liquid Rubber is a two-part, liquid polyurethane system that cures (RTV) to an orange, Shore A50 rubber. This product is very low in viscosity and works very well for pouring large molds (with minimal undercuts) or molds with challenging flow conditions. FormRub 50 can be easily thickened with PolyFiber II Thickener for brush-on application.
