Hexafluorozirconic acid
Hexafluorozirconic acid is mainly used as a corrosion inhibitor in the metal and coatings industry.
Hexafluorozirconic acid shows the highest effectiveness on aluminum though it can also be used on other metals.
Hexafluorozirconic acid is used in non-chromium surface passivation in the surface treatment industry.
Hexafluorozirconic acid is employed as an alternative to nickel-based products with less hazardous properties regarding environmental and health & safety related regulations.
Hexafluorozirconic acid, CAS 12021-95-3 (hexafluorozirconic acid or fluozirconic acid) has the formula H2ZrF6.
Hexafluorozirconic acid is a corrosive chemical, like all salts of fluorosilicic acid.
Hexafluorozirconic acid is used in zirconium oxide thin films for aluminum anodizing, surface treatment applications, electroplating, and chrome-free aluminum lacquering processes.
For metal treatment processes, Fluorozirconic acid and Fluorotitanic acid are often used together in the plating system.
Applications
Electroplating
Aluminum lacquering in chrome-free processes
Synthesis of fluoride-releasing dental monomers, as a precursor of ZrO2 ceramic films as well as metal surface passivation
Hexafluorozirconic acid reduces the occurrence of sludge as a side product – e.g., in Zincphosphate-based systems.

Hexafluorozirconic acid is the replacement of phosphates for the treatment of zinc-galvanized and cold–roll steel
Hexafluorozirconic acid is used for non-chromium surface passivation, an active component in thin-film coatings.
Application of Hexafluorozirconic acid as a corrosion inhibitor in the conversion baths:
For the corrosion protection of light metals or light metal alloys, conversion baths with the corrosion inhibitor hexafluorozirconic acid is used.
The light metals are treated by immersing them in the hexafluorozirconic acid bath for a given time.
A conversion layer forms at this moment, protecting the treated metal from corrosion.
