Composition：It consists of A and B component, A is polyol component, and B is prepolymer ended capping with isocyanate.
Characteristics：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, stable dimension.
Application：Substitution of silicone rubber makes mould for “cultural stone”. It also applies to electrical equipment potting, rubber rollers, rubber plates, rubber wheels, shoe models and other wares.
Storage：Store in a cool and dry place. If you can’t use it up at a time, filling nitrogen gas and then sealing it, or it will easily absorb moisture and go bad. The storage time of original packing is 6 month.
Packing：20Kg or 200Kg galvanized iron drum.
