DESCRIPTIONMC Silicone RTV2 mold making rubber is a two-component material, consisting of Part A base silicone and Part B CA30 curing agent, cures at room temperature by a condensation reaction. These materials can be cast into the cured silicone mold: plaster, polyurethane, PU, GRC, cement, resin, polyester, wax etc...FEATURES1. 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 shrinkageAPPLICATIONSMC Silicone RTV2 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.STORAGEWhen stored at or below 30 C(85F) in the original unopened containers, RTV2 Silicone Base and CA30 Curing agent have a usable life of 10 months from the date of production. After 10 months stockpiles use the Stir to mixing the Part A silicone for some mins, then the silicone can be use again, no influence for other performance.
