Description of Concrete decoration molds making silicone rubber RTV-2 

RTV2 Silicone Rubber is a kind of two-component material. The silicone rubber is made up of Part A base silicone and Part B curing agent. The Part A base silicone and Part B CA curing agent can cure at room temperature by a condensation reaction, after full cure, it become a cured silicone mold. The silicone mold can be cast the following materials for reproduction: plaster, polyurethane, PU, GRC, cement, resin, polyester, wax etc...
