Product Description
MOLD STAR 30
Mold Star™ 30 is an easy-to-use platinum-cure mold silicone. It has a 1A:1B mix ratio by volume. Mold Star silicones have relatively low viscosity. Mold Star™ 30 is a firmer material with a Shore hardness of 30A. The pot life of Mold Star™ 30 is 45 minutes, and it cures in 6 hours at room temperature.
Mold Star™ silicones cure to soft yet strong silicones that are tear-resistant and exhibit very low long-term shrinkage. Molds made with Mold Star™ are long-lasting in your mold library and are excellent for casting wax, plaster, resins, and other materials. Once cured, Mold Star™ silicone withstands heat up to 232 °C and is suitable for casting low-melting-point metals. Note: Mold Star™ silicones are not suitable for brush-on mold making.
Important: This product will not cure against surfaces containing sulfur, even if sealed.
