Mold Star 20T is an easy-to-use Shore 20A translucent platinum silicone that is mixed 1A:1B by volume with no weighing scale necessary. It features 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. Liquid rubber can be thickened with Thi-Vex for brushing onto vertical surfaces. It is easily colored with Silc Pig silicone colorants. Cured molds are used to cast wax, gypsum, resins and more.
