MC Silicone RTV-2 Mold Making Rubber
Condensation cure system
Description of RTV silicone rubber, mold making silicone
RTV silicone rubber, mold making silicone is a two-component material, and the silicone rubber includes Part A base silicone and Part B CA30 curing agent. The Part A base silicone and Part B curing agent can cure at room temperature by a condensation reaction. These silicone materials can be cast into the cured silicone mold: plaster, polyurethane, PU, GRC, cement, resin, polyester, wax etc...
Features of RTV silicone rubber, mold making silicone
1. Good flow ability and long working time
2. Medium hardness
