Section 10 - Stability and Reactivity
Stability

Unstable and decompose light, to heat, causing adeterioration in quality

Conditions to avoid

Direct sunlight, high temperature, high humidity andhigh piling

Incompatibilites with Other Material

There is a possibility to migrate to severe degradation
by hydrolysis with water, and the accumulation of heatof decomposition. Acids, alkalis, heavy metals topromote the decomposition.

Hazardous Decomposition Products

Toxic gases of Carbon Monoxide, Nitrogen Oxides,
Hydrogen chloride, and Sulfur Oxides

Hazardous Polymerization

Will not occur
