Mold Star™ T Series

Mold Star T Series 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 T Series are good for casting wax, gypsum, resins, 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 T Series silicones 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.

Properly cured Mold Star 40T complies with 21 CFR 177.2600(e), water extractable limits for repeated use in aqueous food, "Rubber articles intended for repeated use" with dry food and aqueous food only. Not intended for repeated use in contact with fatty foods.

Cured Mold Star T Series silicones have been tested and certified skin safe by an independent laboratory.
