Alumilite High Strength 3: Available in 1 lb and 5 lbs
Alumilite's High Strength 3 silicone mold making rubber is our most flexible silicone mold making rubber and is great for making molds of parts with deep undercuts or negative drafts. The High Strength 3's flexibility and high tear strength give it the ability to reduce seam lines by making one piece molds rather than multiple piece molds where seam line removal is critical. The High Strength 3 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 3 has a low viscosity which does not require degassing (always recommended when available) and will pick up the exact detail of your original.
