Description of Casting Stone Moldmaking RTV-2 Silicone
Decorative Stone Moldmaking RTV-2 Silicone is a kind of two-component material. The silicone is made up of Part A base silicone and Part B curing agent. The Part A base silicone and Part B CA curing agent can cure at room temperature by a condensation reaction, after full cure, it become a cured silicone mold. The silicone mold can be cast the following materials for reproduction: plaster, polyurethane, PU, GRC, cement, resin, polyester, wax etc...
Characteristics of Casting Stone Moldmaking RTV-2 Silicone
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 Casting Stone Moldmaking RTV-2 Silicone
RTV-2 Silicone 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.
RTV-2066 silicone is a kind of silicone which is especially suitable for the reproduction of artificial stone,cement stone,concrete stone and manufactured stone moldmaking.

FOQ of RTV-2 Silicone Rubber for Mold Making
Why does the RTV liquid silicone rubber for molding have few mold making times?
The silicone rubber mold has few molding times is due to follwoing reasons: adding too much silicone oil which will destroy the molecular of silicone rubber; making the mold for small and fine detailed products with higher hardness silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products.
