Hexafluorozirconic acid (HFZA)

Hexafluorozirconic acid (HFZA) is mainly used as corrosion inhibitor by customers active in the metal and coatings industry. It does show highest effectiveness on aluminium though it can be used on other metals as well. Customers are using Hexafluorozirconic acid as an alternative of nickel based products with less hazardous properties when it comes to environmental as well as health & safety related regulations.

Applications of Hexafluorozirconic Acid include 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
