Description

Zinc Ammonium Chloride CAS NO 14639-97-5 is an inorganic double salt primarily used as a fluxing agent in metalworking and galvanizing processes. Its primary commercial value lies in its ability to promote adhesion and create a clean surface for coating applications, which is critical for product durability and corrosion resistance. This compound is essential for manufacturers in the metallurgy, electronics, and chemical synthesis industries who require reliable surface treatment and soldering solutions.

Application

• Hot-Dip Galvanizing Flux: A key component in the pre-treatment of steel and iron to remove oxides and ensure a uniform, high-quality zinc coating.
• Soldering and Brazing Agent: Used as a flux to clean metal surfaces, prevent re-oxidation, and improve the flow of solder in electronics assembly and plumbing.
• Metal Surface Treatment: Employed in chemical baths for cleaning and preparing metal surfaces prior to painting, plating, or other finishing operations.
• Dry Cell Battery Manufacture: Serves as an electrolyte component in certain types of zinc-carbon batteries.
• Chemical Synthesis: Acts as a catalyst or a source of zinc and ammonium ions in various inorganic and organic synthesis reactions.
• Wood Preservative Formulation: Used in some formulations to impart fire-retardant and anti-fungal properties to timber.

Quality Control

Our Zinc Ammonium Chloride is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise chemical and physical specifications for industrial applications. A Certificate of Analysis (COA) detailing purity, assay, and impurity levels is provided with every shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent caking and degradation from atmospheric moisture.
