Mold Star™ silicones cure to soft, strong rubbers which are tear resistant and exhibit very low long term shrinkage. Moulds made with Mold Star™ will last a long time in your mould library and are good for casting wax, gypsum, resins and other materials. Cured Mold Star™ rubber is heat resistant up to 232°C (450°F) and is suitable for casting low-temperature melt metal alloys. Note: Mold Star™ rubbers are not intended for brush-on mouldmaking.

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