CoastalZinc® Zinc Chloride Uses


Pharmaceutical: Zinc chloride Pharma Grade 99% is used as catalyst for organic synthesis in pharmaceutical and chemical industry.

Dry cell battery: CoastalZinc® Zinc chloride Battery Grade 98% is commonly used in dry cell batteries as an electrolyte.

Water Treatment: CoastalZinc® Zinc chloride used as corrosion inhibitor and scale inhibitor in cooling tower, drinking water and in gas and oil wells.

Galvanizing: ZnCl2 anhydrous 96% is used in fluxes for hot dip galvanizing. It dissolves the dense oxide layer on the metal surface, leaving the metal exposed and ensuring the bonding between the metals. 

Zinc Electroplating: CoastalZinc® Zinc chloride is main source of the zinc in acid zinc plating bath.

Agriculture: ZnCl2 is widely used in agriculture industry. It could be reacted with chelating agents to form solutions of zinc that are biologically available to plants and animals. 

Resins: Zinc chloride anhydrous as an important catalyst in the production of Ion exchange resins. 

Vulcanized Fibre: Vulcanized fibre is a laminate material formed by the reaction and crosslinking of cellulose in a zinc chloride acid bath.  

Rubber: Be used as accelerator in the vulcanizing process of rubber.

Dyestuff: Zinc chloride is used in the dye industry as a stabilizer for color developing salt of ice dye, also can be used in the production of reactive dyes and cationic dyes.

Handling & Storage:

Anhydrous Zinc Chloride should be stored, tightly closed, in a warm and dry place, protected from direct sunlight. Because anhydrous zinc chloride readily absorbs moisture, an inventory turnover rate of about 2-3 months is recommended to minimize the possibility of caking.
