Mold Star™ silicones cure to soft, strong rubbers which are tear resistant and exhibit 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. Cured Mold Star™ rubber is heat resistant up to 450°F (232°C) and is suitable for casting low-temperature melt metal alloys.
Mold Star™ rubbers are mixed 1A:1B by volume (no weighing scale necessary) for precise measurements even at a very low mass and cure at room temperature with negligible shrinkage.
Mold Star™ silicones feature relatively low viscosities making vacuum degassing optional and is not required for most applications. A uniform flow will help minimize entrapped air.
Mold Star™ 19T, 20T, and 31T are translucent silicones for making fast molds or casting into alginate molds. They offer fast cure times, multiple hardnesses, and an infinite number of color effects achieved by adding Silc Pig™ silicone pigments or Cast Magic™ effects powders.
Mold Star™ 16 is available in a 400ml cartridge and is one of the fastest ways to make a silicone mold. With a 6 minute pot life and 30 minute cure time It can even be used in forensics to capture evidence impressions in the field.
