Description of rtv silicon rubber: Silicine rubber for manual moid is flowing liquid with consistant quality in whatever color. It consists of two components, wherein component a is silicone rubber, and component b is curing agent or vulcanizing agent. Firstly process and prepare the model mold or the product to be duplicated, take certain amount of the silicone rubber, add 2-3% solidifying agent, and mix evenly for use. One mold pair can be solidified and formed in 2-3 hours. The formed mold can be used repeatedly without deformation and water shrinkage and with high temperature resistance, thereby providing fast duplication of the product with a product shrinkage 2. The 418 manual mold silicon is mainly applicable to manual molds and small number of product duplication. 25kg/drum, 200kg/drum
