Zinc Chloride - Manufacturer, Supplier & Exporter, kolkata India

East india chemicals Zinc ammonium chloride is the inorganic compound with the formula (NH4)2ZnCl4. It is the ammonium salt of tetrachlorozincate. It used as a flux in the process of hot-dip galvanizing.Zinc chloride is the name of chemical compound ZnCl2 or its hydrates. All zinc chlorides are colorless or white and highly soluble in water. ZnCl2 itself is hygroscopic and can be considered deliquescent. Samples should therefore be protected from sources of moisture, such as the atmosphere.
 

What is zinc chloride used for?

Use in Flux: It is widely used in fluxes for the purpose of tinning, galvanizing and soldering. It is capable of removing salts and oxides from surfaces of various metals. A zinc chloride flux is also known as a 'cleaning agent'.

Uses

Steel to be galvanized passes through an acidic cleaning process to remove iron oxide "mill scale". After this process, the surface of the steel is very active and oxide layers begin forming immediately upon exposure to the atmosphere. Zinc ammonium chloride flux in aqueous solution is applied to the steel to reduce any oxides that are formed and/or inhibit them from forming altogether. This allows the molten zinc in the proceeding galvanizing step to maximally adhere to and alloy with the surface of the steel.

Is zinc chloride dangerous?
 

The aerosol is irritating to the respiratory tract . Corrosive on ingestion. ... The substance may cause effects on the pancreas, if ingested. Acute exposure to high concentrations of zinc chloride fume can lead to Adult Respiratory Distress Syndrome leading to pulmonary fibrosis and death.
