Answer:
Zinc Ammonium Chloride
Explanation:
It acts as a flux, and is coated on steel surface to avoid corrosion of steel with atmospheric air.
Verified answer
Zinc ammonium chloride fluxes are used for all types of galvanizing - after-fabrication galvanizing as well as continuous sheet, wire, and tube galvanizing operations. As flux is a relatively low melting temperature inorganic chemical, the steel sheet cannot be heated to high temperatures ahead of the galvanizing bath.
