storage
B component (isocyanate) is moisture sensitive. Unused raw materials should be stored in a sealed drum,
avoid moisture intrusion .A component (poly) 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. Proposal of process | | Unit | Value | Test Methods |
