10. STABILITY AND REACTIVITY
Reactivity: No data available
Chemical stability: Stable under recommended storage conditions. See Storage, Section 7.
Unstable at elevated temperatures.
Possibility of hazardous reactions: Can occur. Exposure to elevated temperatures can cause
product to decompose and generate gas. This can cause pressure build-up and/or rupturing of closed
containers. Acids.
Conditions to avoid: Avoid temperatures above 50 °C
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.
11. TOXICOLOGICAL INFORMATION
Toxicological information appears in this section when such data is available.
Acute toxicity
Acute oral toxicity
Low toxicity if swallowed. Small amounts swallowed incidentally as a result of normal
handling operations are not likely to cause injury; however, swallowing larger amounts may
cause injury. Observations in animals include: Gastrointestinal irritation.
As product: Single dose oral LD50 has not been determined.
