Zinc Ammonium Chloride Galvanizing Flux

Zinc Ammonium Chloride based Proprietary Galvanizing Flux in Powder form for Wet Flux applications ( LOW FUMING and COST EFFECTIVE )

Zinc Ammonium Chloride.  It is LOW COST formulation for reduced fuming and typically used for continuous galvanizing lines (or new flux charge in a batch process

Zinc Ammonium Chloride Galvanizing Flux is formulated for high speed, low fuming, negligible ash and most importantly thin, strong and uniform Zinc coats 

three types

A flux is used to remove oxide films, promote wetting, and prevent reoxidation of the surfaces during heating. Zinc Ammonium Chloride is used to prepare the flux bath which cleaned iron or steel, usually in sheet form, is passed throughe before going through the galvanizing itself. Intermetallic compounds of iron and zinc are formed on the surface of the steel or iron being treated by heating it in the presence of finely divided zinc below the melting point of the zinc. In another, molten zinc is applied in a fine spray to the surface of the cleaned iron or steel; the zinc adheres tightly to the surface, which ccalls hot-dip process. Commercially solid and triple salt of Zinc Ammonium Chloride are used mainly
