10. STABILITY AND REACTIVITY
NORMALLY STABLE (CONDITIONS TO AVOID):
The product is stable.
Do not mix with oxygen or air above atmospheric pressure. Any source of high temperature, such as lighted
cigarettes, flames, hot spots or welding may yield toxic and/or corrosive decomposition products.
INCOMPATIBILITIES:
Under specific conditions: e.g. very high temperatures and/or appropriate pressures – Freshly abraded aluminum
surfaces may cause strong exothermic reaction. Chemically active metals: potassium, calcium, powdered aluminum,
magnesium and zinc.
HAZARDOUS DECOMPOSITION PRODUCTS:
Halogens, halogen acids and possibly carbonyl halides. These materials are toxic and irritating.
HAZARDOUS POLYMERIZATION:
Will not occur.
