Decription of RTV Silicone Mold Making Rubber
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
Applications of RTV Silicone Mold Making Rubber
Duplication and delicate mold making for poli crafts, resin crafts, concrete decorations, gypsum or plaster products, lighting and candle mold,etc.
