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.


  • Mold Star 20T cures in to a soft, strong rubber that is tear resistant and exhibits 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, 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. 
  • Use IPA Isopropyl to clean up any uncured material.
  • Mold Star 20T has a limited shelf life and should be used as soon as possible.
