Mold Star™ mold 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™ 30 is a harder material, with a 30A Shore hardness.

Features

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, and other materials. Cured Mold Star™ rubber is heat resistant up to 232°C and is suitable for casting low-temperature melt metal alloys. Note: Mold Star™ rubbers are not intended for brush-on moldmaking.

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