Description of RTV-2 Silicone Rubber for Mold Making

RTV-2 is a two-component Room-Temperature-Vulcanizing (RTV-2) silicone rubber. Depending on its curing mechanism, two types of RTV-2 are available: "condensation" cure type and "addition" cure type. In general, RTV-2 Silicone rubber 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 materials can be cast into the cured silicone mold: plaster, polyurethane, PU, GRC, cement, resin, polyester, wax etc...

Features of RTV-2 Silicone Rubber for Mold Making

1. Good flow ability and long working time
2. Medium hardness
3. High tear and tensile strength
4. Easy de-mould from complex replica parts
5. Acid and alkali-resistance
6. Low linear shrinkage

Applications of RTV-2 Silicone Rubber for Mold Making

RTV2 Silicone rubber series are suited for reproduction of cement molding, concrete stones, artificial stones, plaster molding, figures, art objects, decoration molding, GRC products, gypsum products, resin products, PU molds. Etc.
