They are used to dissolve any oxides that have formed on iron or steel surfaces after cleaning and pickling steps of the hot dip galvanizing process. They also prevent further oxides from forming. Fluxes are used as a preflux solution dissolved in water and are used molten on the zinc bath surface. This fluxing process provides metallurgically clean, oxide free steel that will react with clean zinc at about 825 degrees F to form a quality, fully alloyed, galvanized coating.
Fluxes are available in various ratios and with special additive packages to satisfy customer needs.
These fluxes are available in 50lb. Concentrated solution fluxes are available in any ratio of zinc chloride to ammonium chloride. These solution fluxes are shipped in bulk tank trucks, totes and drums. Solution fluxes with special wetting agent are available as well as stable high temperature fluxes to withstand drying and preheat temperatures of up to 600 degrees F . Zaclon galvanizing fluxes are widely used throughout the world for general job shop galvanizing of structures and parts, galvanizing of continuous sheet, continuous wire, continuous fence, pipe and tubular products.
