Why Chose Molding RTV-2 Silicone Rubber ?
Economic Use
As the most stable polymer available, silicones offer superior reliability, excellent service life and reduced production costs.
Versatile Application
Silicone rubbers cure in deep sections as needed for electrical potting and encapsulating, casting rubber parts, arts restoration, general handy crafts, lost wax casting process, plaster forms, seals, stage decorations, statuettes and many more.
Chemical Resistance
Silicones resist acids, bases, solvents, chemicals, oils and water.
General decription of Silicone RTV-2 for Gypsum Mold Making
Silicone RTV-2 for Gypsum Mold Making , Molding Silicone Rubber is generally named as two-part room temperature sulfurated silicone rubber, which features an exceptional fluidity and good operability. When mixed with 2% 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, silicon flexible molds are used for mold duplication and delicate mold making for poli crafts, resin crafts lighting and candle mold,etc.
