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. Unstable at elevated
temperatures.
Possibility of hazardous reactions
Can occur. Elevated temperatures can cause hazardous polymerization.
Conditions to Avoid: Avoid temperatures above 116 °C (241 °F). Elevated temperatures can
cause container to vent and/or rupture. Exposure to elevated temperatures can cause product to
decompose.
Incompatible Materials: Avoid contact with: Acids. Alcohols. Amines. Ammonia. Bases. Metal
compounds. Strong oxidizers. Products based on diisocyanates like TDI and MDI react with many
materials to release heat. The reaction rate increases with temperature as well as with increased
contact; these reactions can become violent. Contact is increased by stirring or if the other material
acts as a solvent. Products based on diisocyanates such as TDI and MDI are not soluble in water and
will 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.
Hazardous decomposition products
Decomposition products depend upon temperature, air supply and the presence of other materials.
Toxic gases are released during decomposition.
