Description of RTV-2 Moulding Silicone for Candle Casting
RTV silicone rubber, RTV-2 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-2 Moulding Silicone for Candle Casting
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 Moulding Silicone for Candle Casting
RTV-2 Silicone 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.
Physical properties of rtv-2 silicone good for pouring
