Cast-A-Mold Platinum is a food grade platinum (addition) cured silicone rubber used for a variety of applications. It exhibits an easy 1:1 mix ratio, low viscosity, excellent tear strength, tensile strength, elongation, heat deflection, and long library life. Cast-a-Mold Platinum can be used to make translucent rubber molds for casting candies, cakes, polyurethanes, epoxy’s, polyester’s, cement, concrete, soap, wax, plaster, etc.. It is user friendly, translucent, FDA compliant, and will cure at room temperature.

Platinum cured silicone rubber can be heat accelerated. For example if you heat the mold  at 150 f the cure time will be reduced from 8 hours to 30 minutes.

Note: For food applications you will need to wash the cured mold with warm water and soap before using.

Addition cured silicone rubber may be inhibited by certain contaminants resulting in tackiness on the surface of the mold. Latex, sulfur based clays, tin cured silicone rubber, amines, nitriles, organo-metallic salt containing compounds should be avoided. If you are unsure of the compatibility of the substrate being molded a small test is recommended. To prevent inhibition it is usually helpful to coat the pattern with a clear acrylic lacquer or paint. Do not use polyurethane or latex.
