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 450¡F (232¡C) and is suitable for casting low-temperature melt metal alloys.

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