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.
