Safety Data Sheet:
|
reactivity |
Not classified as a hazardous reaction |
|
chemical stability |
Exposure to moisture, other isocyanate-reactive materials, or temperatures in excess of 350°F (177°C) may cause polymerization |
|
Possibility of hazardous reactions |
Isocyanates may polymerize if contaminated or exposed to uncontrolled high temperatures. Polymerization can occur if it comes in contact with moisture or other materials that react with isocyanates |
|
Situations to avoid |
Avoid contact with water, amines, strong bases, alcohols and copper alloys. |
|
Incompatible materials |
Strong bases and oxidants, moisture, alcohol content |
|
Hazardous Decomposition Products |
Carbon dioxide, CO, NOx, smoke, isocyanate, isocyanate |
