Introduction of RTV Silicone for Plaster Crafts
RTV Silicone for Plaster Crafts is a two-component material, this kind of silicone 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...
Features of RTV Silicone for Plaster Crafts
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 Silicone for Plaster Crafts
RTV Silicone for Plaster Crafts can be also applied in the field of reproducing cement molding, concrete stones, artificial stones, plaster molding, figures, art objects, decoration molding, GRC products, gypsum products, resin products, PU molds. Etc.
