Mold Star® 19T & 20T

1A:1B Mix By Volume Platinum Silicone Rubber

Mold Star® 19T and 20T are easy to use translucent platinum cure silicones that are mixed 1A:1B by volume (no weighing scale necessary). They feature a relatively low viscosity and vacuum degassing is not required for most applications.

Mold Star® 19T and 20T cure 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 and 20T silicones can be thickened with THI-VEX® thickener for brushon 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® 19T and 20T are heat resistant up to 450°F (232°C) and are suitable for casting low-temperature melt metal alloys.

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