Sourcing Zinc Chloride? ChemicalDekho connects you with specialized inorganic manufacturers like Rubamin and diverse specialized importers. Access high-purity salts for batteries, metallurgy, and wood preservation.
Zinc Chloride (CAS 7646-85-7) is a powerful Lewis acid. It is the primary electrolyte in Leclanche dry cell batteries and a critical flux in hot-dip galvanizing and soldering. In the timber industry, it preserves wood against fungal attack and insects. Listings cover high-assay anhydrous powder and convenient concentrated liquid solutions.
Verified listings ensure strict control over lead and iron impurities, essential for battery performance and clear chemical synthesis.

Causes severe skin burns and eye damage. Harmful if swallowed. Very toxic to aquatic life. Extremely hygroscopic—solid can liquify just by absorbing air moisture.
In Zinc-Carbon batteries, Zinc Chloride acts as the electrolyte that allows ions to flow between the anode and cathode, providing the electrical current.
A flux is a chemical cleaner used before soldering or galvanizing. Zinc Chloride dissolves metal oxides on the surface, allowing the molten solder or zinc to bond perfectly with the base metal.
No. Zinc Chloride (ZnCl2) is very corrosive and used for industrial processes. Zinc Sulfate (ZnSO4) is a milder salt used mainly as a fertilizer and feed supplement.
Yes, 50% and 70% solutions are very common as they are easier for galvanizing plants to dose into their tanks.
