Mold Star 31T is an easy to use translucent platinum cure silicone that is mixed 1A:1B by volume (no weighing scale necessary). Features a relatively low viscosity and vacuum degassing is not required for most applications.

Mold Star 31T cures to 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 31T 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 31T 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.
