Zinc Chloride - Stability & Reactivity

Stability
Normally stable.
Hazardous Polymerization
Will not occur.
Incompatibility - Materials To Avoid
POTASSIUM - a mixture of potassium and zinc chloride is sensitive to mechanical shock and produces a strong explosion on impact.(35,36) STRONG BASES (e.g. alkali hydroxides) - react vigorously or violently, with the evolution of heat.(33)
Hazardous Decomposition Products
None reported at normal temperatures.
Conditions To Avoid
High temperatures.
Corrosivity To Metals
Zinc chloride attacks carbon steel (such as types 1010 and 1020), cast iron, some stainless steels (such as types 303, 310, 321, 400 series), aluminum, bronze, other bronze alloys, such as aluminum bronze, naval bronze, silicon bronze, brass and admiralty brass at normal temperatures. It does not attack high silicon iron, silicon-copper, types 20 Cb-3 and 316 stainless steels, nickel (up to 80% solution), nickel-base alloys, such as Hastelloy, tantalum, titanium and zirconium at normal temperatures.(37,38,39).
Corrosivity To Non-Metals
Zinc chloride attacks plastics, such as nylon, and elastomers, such as polyacrylate, chlorinated polyethylene and polysulfides. It does not attack most plastics, such as acrylonitrile-butadiene-styrene (ABS), acrylics, chlorinated polyvinyl chloride (CPVC), polyesters, polyethylene, polypropylene, polyvinyl chloride (PVC) and Teflon; elastomers, such as butyl rubber, chloroprene, ethylene-propylene, Viton A and other fluorocarbons, natural rubber, isoprene, neoprene, Nitrile Buna-N (NBR), and silicon rubbers; and coatings, such as epoxy and vinyls.
