Polyurethane Casting Resin for Moulding
It is a double component polyurethane resin including part A and B. A is polyol and B is prepolymer ended capping with isocyanate.
It is special for casting concrete moudling. It is a substitution of silicone rubber making mould for “cultural stone”. It also applies to make electrical equipment potting, rubber roller, rubber plates, rubber wheels, shoe models and other wares.
It has excellent processing properties, solidification in common temperature, short time of demould, and regulating colors by adding pigment. The ware has good properties of abrasive resistance, waterproof, transparent, good elastic, and stable dimension.
