Application
-Mainly used in the production of large quantities of polyurethane elastomer products, such as a variety of rollers, skateboard wheels, fitness equipment, rubber, industrial parts, etc.

Usage method
-The utility model is mainly suitable for the operation of the middle and low temperature pouring machine, and can be operated manually by adjusting. The use of two components, the ratio of 100:100 or 100:50~100.

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.
