Galvanizing Flux

A solution, usually in the form of a blanket 50 to 75 mm (1.97 to 2.95 in.) thick, on the surface of the molten zinc, through which wires pass before entering the galvanizing bath. Its purpose is to remove impurities from the surface of the wire and assist adhesion of the zinc coat to the wire. Also used in a separate tank followed by a drying tunnel before passing into a zinc bath.
