Multipurpose silicone is a two part silicone rubber, which cures at room temperature within 2 5 hours depending on the percentage catalyst added. It has excellent flow ability and is easy to demould. The rubber has good tensile and tear strength combined with low shrinkage. Multipurpose silicone is suitable for casting Polyester resins, polyurethane, plaster, candle wax, and soap.
