Zinc Chloride is a white crystalline solid with strong hygroscopic properties and very high water solubility. Its chemical formula is ZnCl₂ and its molecular weight is approximately 136.28 g/mol.

What Is Zinc Chloride?

Zinc Chloride (ZnCl₂) is an inorganic zinc salt consisting of zinc and chloride ions. It is widely used as an industrial chemical because of its high water solubility, Lewis acid properties and ability to provide zinc ions in chemical processes.

It is also known as Zinc Dichloride, and the anhydrous compound is identified by CAS No. 7646-85-7.

Because Zinc Chloride is highly hygroscopic, it should be stored in tightly sealed containers and protected from moisture during storage and transportation.

Main Applications of Zinc Chloride

1. Electroplating

Zinc Chloride is widely used in electroplating processes as a source of zinc ions and as a component of plating solutions.

It can be used in:

  • Zinc electroplating

  • Zinc alloy plating

  • Metal surface treatment

  • Electroplating bath formulations

  • Metal surface activation

Its high water solubility makes Zinc Chloride suitable for preparing zinc-containing plating solutions.

2. Soldering and Flux

Zinc Chloride is commonly used as an active component in soldering fluxes.

Zinc Chloride-based fluxes can help remove metal oxides from metal surfaces during soldering and improve the wetting and bonding of solder.

Typical applications include:

  • Soldering flux

  • Welding flux

  • Metal joining

  • Tin and zinc soldering

  • Metal surface cleaning

3. Chemical Manufacturing

Zinc Chloride is used as a zinc source, catalyst and processing aid in various chemical manufacturing processes.

It can be used for:

  • Organic synthesis

  • Chemical intermediates

  • Zinc-containing compounds

  • Catalyst systems

  • Resin and polymer processing

  • Production of other zinc salts

Zinc Chloride is also used as a Lewis acid and catalyst in certain chemical reactions.

4. Metal Treatment

Zinc Chloride can be used in metal treatment and metallurgical applications, particularly where zinc ions or surface activation are required.

Applications include:

  • Metal surface preparation

  • Oxide removal

  • Metal cleaning

  • Zinc-related metallurgical processes

  • Surface treatment formulations

5. Textile Industry

Zinc Chloride has applications in textile processing, including certain formulations used as mordants, sizing agents and processing aids.

It can also be used in specialized fiber and cellulose processing.

6. Battery and Electrochemical Applications

Zinc Chloride can be used as a raw material or electrolyte component in certain battery systems and electrochemical applications.

Its high solubility and zinc-ion availability make it suitable for specific electrolyte formulations.

7. Wood Preservation and Other Industrial Applications

Zinc Chloride has also been used in wood preservation and flame-retardant formulations, as well as in certain paper, rubber and industrial chemical applications.
