What Is Zinc Chloride Used For?
Zinc Chloride serves a wide range of industries, each relying on its distinct chemical properties: strong Lewis acidity, high water solubility, oxide-dissolving ability, and effectiveness as a desiccant and electrolyte.
Galvanizing & Metalworking
Galvanizing Flux and Soldering Flux
Zinc Chloride is the foundational raw material for galvanizing flux and soldering flux in the steel and metalworking industries. In hot-dip galvanizing, ZnCl₂ is applied as a pre-treatment bath chemical that reacts with iron oxide layers on the steel surface, dissolving them and exposing a clean, reactive metal surface for zinc coating. When heated, the chloride species attack metal oxides and convert them into volatile or soluble salts, allowing molten zinc to wet and bond metallurgically with the base steel. In soldering, Zinc Chloride-based flux prevents re-oxidation of the joint surfaces during heating, enables solder to flow freely, and ensures strong, low-porosity bonds particularly on iron, steel, brass, and galvanized surfaces. Our Anhydrous and Technical grades are used by galvanizing lines and flux manufacturers who require consistent chloride activity and tight metal impurity limits.
Battery Manufacturing
Electrolyte in Dry Cell Batteries
Zinc Chloride functions as the electrolyte in zinc chloride-type Leclanché dry cell batteries, which are widely used in consumer electronics, remote controls, flashlights, and portable devices. In these cells, the aqueous Zinc Chloride electrolyte serves a dual purpose: it conducts ionic current between the zinc anode and manganese dioxide cathode, and it acts as a pH buffer and moisture-retaining agent that extends battery shelf life and prevents the cathode from drying out during storage. Zinc chloride cells outperform conventional zinc-carbon batteries in terms of capacity under moderate to heavy drain conditions and have better low-temperature performance. Technical grade Zinc Chloride is standard for battery electrolyte formulations where consistent ionic conductivity and controlled impurity levels directly affect cell performance and cycle life.
Textile Processing
Mercerising Agent and Durable-Press Catalyst
In the textile industry, concentrated Zinc Chloride solution is used as a mercerising agent for cotton fabrics, where it swells the cellulose fibre structure and improves lustre, dye uptake, and tensile strength. A 64% Zinc Chloride solution is particularly effective at dissolving and regenerating cellulose, making it useful in the production of vulcanised fibre and certain technical textile substrates. At lower concentrations, Zinc Chloride serves as a catalyst in resin finishing systems that impart durable-press, wash-and-wear, and wrinkle-resistance properties to cotton and cotton-synthetic blend fabrics. Unlike some alternative catalysts, Zinc Chloride has limited impact on dye shades in tinted materials and does not cause significant resin yellowing on white goods, making it a preferred choice in textile finishing operations that process both coloured and white fabric in the same facility.
Chemical Synthesis
Lewis Acid Catalyst in Organic Chemistry
Anhydrous Zinc Chloride is a widely used Lewis acid catalyst in industrial organic chemical synthesis. It catalyses Friedel-Crafts acylation and alkylation reactions, is a key component of the Lucas reagent (anhydrous ZnCl₂ in concentrated HCl) used to distinguish and prepare alkyl chlorides from alcohols, and promotes Fischer indole synthesis. In its molten state, ZnCl₂ catalyses the aromatisation of certain hydrocarbons, including the production of hexamethylbenzene from methanol. The anhydrous form is essential for the synthesis of organozinc reagents used in palladium-catalysed Negishi coupling reactions with aryl and vinyl halides, a methodology of sufficient scientific significance that it was recognised by the 2010 Nobel Prize in Chemistry. Its relatively low cost and anhydrous character make it the industrial catalyst of choice for many of these transformations compared with more expensive metal halide alternatives.
Wood Preservation
Wood Preservative and Fire Retardant
Zinc Chloride has been used as a wood preservative for over a century, applied by pressure-impregnation processes where it penetrates deeply into timber to protect against fungal decay, wood-rotting organisms, and insect attack. In wood treatment formulations, Zinc Chloride is typically combined with other preservatives to broaden its biocidal spectrum and reduce leaching. It also functions as a fire retardant in treated timber applications, where its presence in the cell wall structure inhibits the combustion of the cellulose matrix. Commercial grade Zinc Chloride is generally specified for wood treatment applications, where the priority is effective delivery of the zinc ion into the wood substrate at an economically viable cost, rather than the tighter assay and impurity limits required in chemical synthesis or galvanizing applications.
Activated Carbon Production
Chemical Activation Agent for Activated Carbon
Zinc Chloride is one of the most widely used chemical activation agents in the production of activated carbon from cellulosic and lignocellulosic raw materials such as wood, bamboo, agricultural residues, and certain industrial by-products. In the chemical activation process, the raw material is impregnated with a concentrated Zinc Chloride solution, then pyrolysed at elevated temperatures under controlled conditions. The ZnCl₂ acts as a dehydrating and oxidising agent during pyrolysis, promoting the development of a highly porous microstructure with large surface area in the resulting carbon. After activation, the Zinc Chloride is recovered by water washing of the product and recycled back into the process. The activated carbon produced by ZnCl₂ activation typically has a predominantly microporous structure particularly suited for adsorption of dissolved organic compounds in liquid-phase purification applications including water treatment, food and beverage processing, and pharmaceutical manufacturing.

Frequently Asked Questions
The chemical formula of Zinc Chloride is ZnCl₂. Its CAS number is 7646-85-7 and its molecular weight is 136.29 g/mol. It is a white crystalline, hygroscopic, and deliquescent solid that is highly soluble in water, ethanol, glycerol, ether, and acetone. It melts at 290°C and boils at 732°C. Meghachem manufactures ZnCl₂ in Anhydrous (98-99%), Technical (90-92%), and Commercial (80-85%) grades, supplied in HDPE bags with PP inner liners in 25 kg and 50 kg pack sizes.
Anhydrous grade (98-99% assay) has the lowest impurity profile, with ammonia below 1%, alkalies and alkaline earth metals below 1%, and metal impurities below 10 ppm. It is specified for applications where purity directly affects product performance — galvanizing flux, pharmaceutical excipients, and organic chemical synthesis. Technical grade (90-92% assay) suits general industrial uses including standard flux formulation, battery electrolyte, and textile processing. Commercial grade (80-85% assay) has higher ammonia content of 10-15% and is used where cost efficiency takes priority over purity, such as wood preservation treatments and some lower-specification flux preparations. For any application requiring a COA with specific impurity limits, Anhydrous or Technical grade is recommended.
In hot-dip galvanizing, Zinc Chloride acts as a chemical flux by dissolving iron oxide layers on the steel surface. When the steel article enters the flux bath and is subsequently heated, ZnCl₂ releases active chloride species that react with iron oxides (Fe₂O₃, Fe₃O₄), converting them into volatile or water-soluble iron chloride salts. This exposes a clean, reactive steel surface free of oxide contamination. When the flux-coated steel article then enters the molten zinc bath, the clean iron surface enables the zinc to wet and react metallurgically with the steel, forming a continuous, adherent zinc-iron intermetallic coating. Zinc Chloride is often combined with Ammonium Chloride in double-salt flux formulations, where the two components together provide broader oxide dissolution and improved flux bath stability at higher operating temperatures.

Zinc Chloride is corrosive to skin, eyes, and mucous membranes and requires standard industrial chemical handling precautions. Chemical-resistant gloves (nitrile or neoprene), safety goggles, and appropriate respiratory protection should be used when handling the powder, as airborne dust can irritate the respiratory tract. In case of skin contact, wash the affected area immediately with large amounts of water for at least 15-20 minutes and remove contaminated clothing. Eye contact requires immediate flushing with water and medical attention. Zinc Chloride solution is acidic and similarly corrosive. It is acutely toxic to aquatic life and must not be discharged into watercourses untreated. Full safety handling details are provided in the Material Safety Data Sheet, which is supplied with every shipment from Meghachem.
