| RTV2 Silicone Rubber is a kind of two-component material. The silicone rubber 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... |
| 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 |
