Zinc Ammonium Chloride Salts

We produce Double, Triple and Single salts as well as any combination of zinc chloride and ammonium chloride, according to customer requirements.
The solutions of zinc chloride and ammonium chloride are known as flux bath. The most frequent combination of this salt is formed by one molecule of zinc chloride and two of ammonium chloride (called double salt).


Fluxing solutions are mainly used in hot-dip galvanizing for pre-treatment of steel surfaces. This double salt solution is stored at an approximate concentration of 500 g / l and a temperature around 60 degrees C into which the pieces are dipped after pickling and washing and are then inserted into the molten zinc bath.

The main function of flux is to prevent oxidation of the metal before it contacts the zinc bath.

The solutions are also widely used for pre-treatment of metals before welding, and in the tin immersion process.
