Mold Star 20T

Mold Star 20T is an easy to use translucent platinum silicone that features a relatively low viscosity and vacuum degassing is not required for most applications.

• Moulds made with Mold Star will last a long time in your mould library and are good for casting wax, gypsum, resins, concrete and other materials.
• Mold Star 20T silicone can be thickened with Thi-Vex® thickener for brush-on application and effects.
• Mold Star 20T is heat resistant up to 232°C (450°F) and is suitable for casting low-temperature melt metal alloys.
• Note: This product will not cure against surfaces containing sulphur, even when sealed.
