Pu Shoe Upper Resin
Pu Shoe Upper Resin
COMPOSITION
This system is consist of four components, polyol, ISO, curing agent and catalyst.
CHARACTERISTICS
Mixing Temperature 30～40℃, Curing Temperature 80～90℃, Demould time 8～10 min (adjustable), the Hardness of finished product could be adjusted by changing the materials ratio of component A+C/B.
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.
