Mold Star 20T is an easy to use Shore 20A translucent platinum silicone that is mixed 1A:1B by volume (no weighing scale necessary). It features a relatively low viscosity and vacuum degassing is not required for most applications. Pot life is 6 minutes and cure time is 30 minutes at room temperature. Mold Star 20T cures into a soft, strong rubber that is tear resistant and exhibits very low long term shrinkage. Molds made with Mold Star will last a long time in your mold library and are good for casting wax, gypsum, resins, concrete and other materials. Mold Star 20T silicone can be thickened with Thi-Vex thickener for brush-on application and effects. An infinite number of color effects can be achieved by adding Silc Pig silicone pigments or Cast Magic effects powders. Mold Star 20T is heat resistant up to 450F (232C) and is suitable for casting low-temperature melt metal alloys.

Note: This product will not cure against surfaces containing sulfur, even when sealed.
