Pu Mould Resin

Pu Mould Resin

COMPOSITION It consists of A&B component, A is polyol, and B is Iso-terminated polyurethane prepolymer. CHARACTERISTICS It has excellent processing properties, short gel time, solid in common temperature. The finished product has good properties of abrasion resistance, anti-hydrolyzing, transparence, good resilience and stable dimension. APPLICATION Used for making shoe and different kind of PU moulds. Substitute of Silicon rubber to make the mould of cultural stone. STORAGE Store in a cool and dry place. If you can’t use one drum up at one time, please fill Nitrogen gas and seal the drum well. The shelf life of original packing is 6 months. PHYSICAL PROPERTIES
