Polyurethane Mould Glue
l
Composition
It consists of A and B component, A is polyol component, and B is prepolymer ends capping with isocyanate.
l
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.
l
Application
Substitution of silicone rubber makes mould for cultural stone. It also applies to electrical equipment potting, rubber roller, rubber plate, rubber wheel ,shoe model and other wares.
l
Storage
Store in a cool and dry place. If you cant use it up at a time, filling nitrogen and then sealing it, or it will easily absorb moisture and go bad. The storage time of original binding is 6 month.
