Hexafluorozirconium acid 45 % is used commonly in industrial settings as a precursor material for the manufacture of films used to coat ceramics, to synthesize glass used in prescription eyeglasses and as a common corrosion inhibitor on steel and other metal surfaces.
Hexafluorozirconium acid 45 % is a colorless, odorless liquid mixture, completely soluble in water and stable under recommended storage conditions.
Hexafluorozirconium acid is corrosive to metals.
Hexafluorozirconium acid is incompatible with strong acids, bases, and should be stored away from metals as contact with metals can result in the release of hydrogen gas that can be explosive.
This mixture is predominantly composed of 45% dihydrogen Hexafluorozirconium (2-), 54.5% water and hydrofluoric acid comprising approximately 0.5%.
Given its major uses, the primary exposure to this chemical occurs in the industrial setting.
For workers, good manufacturing and industrial hygiene practices should be followed to prevent or reduce exposure.
Workplace exposure limits for have been established for use of this product in worksite safety programs.
See the Safety Data Sheet (SDS) for additional information.
In contact with fire, hexafluorozirconium acid 45 % decomposes to release hazardous hydrogen fluoride.
Fire or intense heat may cause its outer package to rupture violently so it should be stored under controlled room temperatures.

Hexafluorozirconium acid is a solution of dihydrogen Hexafluorozirconium acid containing a small percentage of hydrogen fluoride and used in the phosphating process for metal plating.
Hexafluorozirconium acid is an alternative to nickel in this process because nickel is subject to environmental regulation.
Hexafluorozirconium acid reduces considerably the formation of sludge byproducts compared to zinc-phosphate-based systems and it also can be plugged into production lines easily, with little or no modifications.
Hexafluorozirconium acid is the preferred choice when replacing zinc-phosphate ahead of an electrocoat painting system.

The acid and its salts are used in metal surface technolog
