1 Gal. RTV Silicone Rubber Liquid Mold Making Casting Kit

1 Gallon RTV Silicone Mold Making Rubber High Strength Liquid for Molding & Casting

RTV Silicone Rubber is specially used for mold making applications where greater dimension stability is required. It has excellent tear strength. It is two component system which cures in 24 hours at 25°C. To accelerate curing process, elevated temperature may be used(at 60°C for 120 min or 170°C for 10 min). It can be used to cast epoxy, polyester, soap, concrete, candies, Polyurethane, cement, fiberglass resin, etc.
