Polymerization occurs without formation of heat. Features of RTV-2 silicone for architectural restoration moulding 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 RTV-2 silicone for architectural restoration moulding RTV-2 Silicone 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. Physical properties of RTV-2 silicone good for pouring or brushing Item No.: RTV2028 Color: White Viscosity: 32000 cps Hardness: 28 shore A Tensile strength: 4.2 Mpa Tear strength: 31 N/mm Elongation: 510% Pot life: 30-40 mins Mix ratio: 2% Curing time: 4-6 hours Storage of RTV-2 molding silicone rubber When the silicone rubber is stored at or below 30 centi degree in the original unopened containers, RTV2 Silicone Base and CA30 Curing agent have a usable life of 10 months from the date of production.
