Description
Mold Star™ 31T is an easy to use Shore 31A 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 5 minutes and cure time is 23 minutes at room temperature.
Mold Star™ 31T cures in 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. 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.
Cured Mold Star™ 19T, 20T and 31T silicones have been tested and certified skin safe by an independent laboratory.
Note: This product will not cure against surfaces containing sulfur, even when sealed.
