Zinc Chloride 98% – Essential Chemical for Fluxing, Synthesis, and Treatment Processes
We supply high-purity zinc chloride with a guaranteed assay of 98%. This versatile inorganic compound acts as a powerful flux, catalyst, and preservative. Consequently, manufacturers across multiple industries actively use it for metal welding, chemical synthesis, and wood preservation. Moreover, its hygroscopic nature and solubility make it indispensable for specialized industrial and treatment applications.
Core Industrial Applications and Uses
Zinc chloride serves critical functions in metalwork, chemical production, and material preservation. Its applications are both diverse and technically specific.
First, the metalworking and galvanizing industry relies on zinc chloride 98% as a primary flux agent. It cleans metal surfaces by removing oxides, thereby ensuring strong, clean solder joints in welding and galvanizing. Therefore, fabricators depend on it for quality assurance in automotive, construction, and electronics assembly.
Second, the chemical manufacturing sector utilizes it as a key catalyst and precursor. It facilitates organic synthesis reactions, such as the production of dyes and pharmaceuticals. Furthermore, it is essential for manufacturing activated carbon and for oil-gas well treatment fluids to improve permeability.
Third, wood treatment and preservation companies employ it as an effective fire-retardant and preservative. It protects lumber from decay, insects, and flame spread. Additionally, it finds use in battery electrolytes, textile processing, and as an astringent in antiseptic and deodorant products.
