Mold Star 19T 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 19T 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 19T 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.

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