Description of RTV-2 Silicone Rubber for Stone Mold Making

RTV-2 silicone rubber is a two-component material, this kind of silicone rubber consists of Part A base silicone and Part B CA30 curing agent, and Part A base silicone and Part B curing agent can cure at room temperature by a condensation reaction. These materials can be cast into the cured silicone molds: plaster polyurethane, PU, GRC, cement, resin, polyester, wax etc...
