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.

The color of polyurethane Part Bs may change in color from batch to batch or may darken with age, but product performance is not affected. For additional physical property specifications, refer to the Physical Properties Bulletin.
FormRub Series liquid polyurethane rubbers are designed to make high-performance molds that stand up to the rigors of high-production casting and forming of concrete. In addition to concrete, FormRub molds are often used to cast plaster and wax. With use of an appropriate release agent, some resins can also be cast in FormRub molds.
