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® 20T is a translucent silicone for making fast molds or casting into alginate molds. Mold Star® 20T cures in 30 minutes at room temperature and it offers 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.
