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