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.
One to One Mix Ratio
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.
No Vacuum Degassing
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.
Make Molds Fast
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.
