Easy to Use Silicone Mold Rubber

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, concrete and other materials. Cured Mold Star™ rubber is heat resistant up to 450°F (232°C) and is suitable for casting low-temperature melt metal alloys.

NOTE: This product will not work with modeling clays containing sulfur under any circumstances.

One to One Mix Ratio

Mold Star™ rubbers are mixed 1A:1B by volume (no weighing scale necessary) for precise measurements even at a very low mass and cure at room temperature with negligible shrinkage.

No Vacuum Degassing

Mold Star™ silicones feature relatively low viscosities making vacuum degassing optional and is not required for most applications. A uniform flow will help minimize entrapped air.

Translucent Options

Make Fast Cut Molds or Castings

Mold Star™ 19T, 20T, and 31T are translucent silicones for making fast molds or casting into alginate molds. They offer fast cure times, multiple hardnesses, and an infinite number of color effects achieved by adding Silc Pig™ silicone pigments or Cast Magic™ effects powders.
