Abstract (en)
[origin: EP2725115A1] This invention relates to a flux composition for treating a metal surface, comprising (a) more than 40 and less than 70 wt.% zinc chloride, (b) 10 to 30 wt.% ammonium chloride, (c) more than 6 and less than 30 wt.% of a set of at least two alkali metal chlorides including sodium chloride and potassium chloride, (d) from 0 to 2 wt.% lead chloride, and (e) from 0 to 15 wt.% tin chloride, provided that the KCl/NaCl weight ratio of said set of at least two alkali metal chlorides ranges from 2.0 to 8.0. This invention also relates to a fluxing bath comprising this flux composition dissolved in water for use in galvanizing processes, by batch or continuously, of metal articles such as iron or steel long products and flat products including wires, plates, coils, rods, reinforcing bars, tubes, strips and sheets.
