10. Stability and Reactivity
Reactivity
No dangerous reaction known under conditions of normal use.
Chemical stability
Stable under recommended storage conditions. See Storage, Section 7.
Possibility of hazardous reactions
Can occur. Elevated temperatures can cause hazardous polymerization. Polymerization can be
catalyzed by: Strong bases. Water.
Conditions to Avoid: Exposure to elevated temperatures can cause product to decompose.
Elevated temperatures can cause pressure buildup in closed containers due to the release of blowing
agents. Generation of gas during decomposition can cause pressure in closed systems. Pressure
build-up can be rapid. Avoid moisture. Material reacts slowly with water, releasing carbon dioxide
which can cause pressure buildup and rupture of closed containers. Elevated temperatures accelerate
this reaction.
Incompatible Materials: Avoid contact with: Acids. Alcohols. Amines. Water. Ammonia. Bases.
Metal compounds. Moist air. Strong oxidizers. Diisocyanates react with many materials and the rate
of reaction increases with temperature as well as increased contact; these reactions can become
violent. Contact is increased by stirring or if the other material mixes with the diisocyanate.
Diisocyanates are not soluble in water and sink to the bottom, but react slowly at the interface. The
reaction forms carbon dioxide gas and a layer of solid polyurea. Reaction with water will generate
carbon dioxide and heat. Avoid contact with metals such as: Aluminum. Zinc. Brass. Tin. Copper.
Galvanized metals. Avoid contact with absorbent materials such as: Moist organic absorbents. Avoid
unintended contact with polyols. The reaction of polyols and isocyanates generate heat.
Hazardous decomposition products
Decomposition products depend upon temperature, air supply and the presence of other materials.
Gases are released during decomposition.
