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, 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.
Details: Mold Star mold rubbers are easy to use platinum silicones which are mixed 1A:1B by volume (no weighing scale necessary). Mold Star silicones feature relatively low viscosities and vacuum degassing is not required for most applications. Mold Star 30 is a harder material, with a 30A Shore hardness.
