Rtv-2 Silicone Rubber For Molding

Rtv-2 Silicone Rubber For Molding is a kind of two-component material. It 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 rtv 2 silicone rubber

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

RTV-2 silicon liquid operations
If the customer wants to make large products and large size molds, the mold should be made of silicon liquid with high hardness. On the contrary, if the mold with fine and precision patterns, it should be made of silicon liquid with low hardness.
