-Mainly used in the production of ordinary polyurethane elastomer products, such as a variety of industrial components, roller, rubber roller, rubber, oil seal, cushioning materials, plates, etc..

Usage method
-Suitable for manual and high temperature casting machine operation, chain extender is MOCA.

-The prepolymer should be stored at low temperature and dry place, avoid the moisture and moisture when used
-After the opening of the prepolymer should be used up as soon as possible, if not exhausted with nitrogen seal.
-The storage period of unopened prepolymer is three months.
-If you want to add color paste or other materials, keep the water content below 0.1%, and consider the compatibility of additives.
