Alumilite's High Strength 2 silicone mold making rubber has an extremely high tear strength and is great for making almost any kind of mold. The High Strength 2 is a 20-25 A shore hardness which means it is soft enough to use for parts with undercuts but still has enough stiffness to effectively make multiple piece molds and maintain good alignment. The High Strength 2 is a tin base silicone and cures against all different types of clay and substrate. The tin base silicone is a condensation cure and therefore temperature and humidity may affect the cure speed of the rubber. The High Strength 2 has a low viscosity which does not require degassing (always recommended when available) and will pick up the exact detail of your original.  Use Alumilite's Rubber to Rubber mold release or petroleum jelly when making 2-piece molds when using the High Strength 2 rubber due to it's extremely high tear strength.
