Smooth-On Mold Star 16 FAST - Platinum Cure Molding Silicone

Mold Star rubbers are easy to use platinum silicones which are mixed 1A:1B by volume (no weighing scale necessary). Mold Star silicones feature relatively low viscosities and vacuum degassing is not required for most applications. Mold Star 16 FAST is a faster material with a 6 minute pot life and 30 minute cure time. 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.

Each kit contains 1 pint of part A and 1 pint of part B

Note: THI-VEX is NOT compatible with Mold Star rubbers.

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