“Alumilite's High Strength 3 silicone mould making rubber is our most flexible silicone mould making rubber and is great for making moulds 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 moulds rather than multiple piece moulds 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. Use Alumilite's Rubber to Rubber mould release or petroleum jelly when making 2-piece moulds when using the High Strength 3 rubber due to its extremely high tear strength.”
