Garden Decoration Mould Making RTV-2 Silicone Rubber
RTV-2 silicone rubber is generally named as two-part room temperature vulcanized silicone rubber, which features an exceptional fluidity and good operability. When mixed with 2-3% curing agent, they can still be operated within 30 minutes, but will be formed after 4-6 hours. With resistance to deformation, high temperature, acid and alkali, and expansion.
RTV-2 silicone rubber, mold making silicone rubbers 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.
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

Production Process of RTV-2 silicone rubbers
Part A base silicone: 5kg, 20kg/drum, 25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 250g, 800g/bottle, 1kg/bottle
Storage of RTV-2 Silicone for garden decoration moulding
When the silicone rubber is stored at or below 30 centi degree in the original unopened containers, Silicone Base and Curing agent have a usable life of 10 months from the date of production. After 10 months stockpiles use the Stir to mix the Part A silicone for some minutes, then the silicone can be use again, no influence for other performance.
