DESCRIPTIONSILASTIC RTV2030 mold making rubber is a two-component material, this kind of silicone rubber 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 1. Good flowability and long working time2. Medium hardness3. High tear and tensile strength4. Easy de-mould from complex replica parts5. Acid and alkali-resistance6. Low linear shrinkageAPPLICATIONSSILASTIC RTV2030 rubber is suited for reproduction of middle size cement molds, concrete stones, artificial stones, plaster molds, figures, art objects, decoration molds, GRC products, gypsum products, resin products, PU molds.
