storage

B component (isocyanate) is moisture sensitive. Unused raw materials should be stored in a sealed drum,

avoid moisture intrusion .A component (polyether) should stir well before use.
 

Potential hazards

Part B (isocyanates) stimulate the eye, respiratory and skin through breathing and skin contact ,and possibly sensitization.

When contact part B ( isocyanates) , necessary preventive measures should be taken according to material safety date sheet (MSDS) .
 

Waste disposal

With reference to the material safety date sheet (MSDS) of the product ,or deal with it in accordance with local

laws and regulations.
