Zinc Chloride (Anhydrous)

Zinc chloride (ZnCl2), white rod-shaped, granular or powdery crystal, density 2.91 g/cm3, melting point 283℃, boiling point 723℃, tasteless, strong moisture, can absorb water from the air and dissolve. Zinc chloride is soluble in water, and its solution is acidic. Soluble in methanol, ethanol, propanol, ether and other organic solvent. Insoluble in liquid ammonia. The molten zinc chloride has a good electrical conductivity. Zinc chloride is toxic, corrosive, should be sealed storage.

Coastal Zinc ® Zinc Chloride Uses

Pharmaceutical: Zinc chloride (anhydrous) is used as catalyst for organic synthesis in pharmaceutical and chemical industry.

Dry cell battery: It is commonly used in dry cell batteries as an electrolyte.

Water Treatment: It is used as corrosion inhibitor and scale inhibitor in cooling tower, drinking water and in gas and oil wells.

Galvanizing: ZnCl2(anhydrous) 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: 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.

Paints: 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.
