Application

-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.


Attention

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.
