Description

Stannous Chloride is an essential inorganic compound widely used as a powerful reducing agent and catalyst in industrial chemistry. Its unique chemical properties make it a critical raw material for processes requiring precise control over oxidation states and tin ion introduction. This product is indispensable for manufacturers in the electronics, plating, polymer, and pharmaceutical industries seeking reliable and high-purity tin sources.

Application

• Electroless Tin Plating & Electroplating: A key component in baths for depositing tin and tin alloy coatings on metals, providing excellent solderability and corrosion resistance for electronic components and connectors.
• Chemical Synthesis & Catalysis: Acts as a selective reducing agent in organic synthesis and as a catalyst in various polymerization reactions, including the production of polyurethane foams and polyesters.
• PVC Stabilizer: Functions as a highly effective heat stabilizer in the manufacture of rigid and flexible polyvinyl chloride (PVC) products, preventing degradation during processing.
• Pharmaceutical Intermediate: Used in the synthesis of specific active pharmaceutical ingredients (APIs) and as a reagent in certain diagnostic chemical processes.
• Glass & Ceramic Manufacturing: Employed to create conductive coatings on glass surfaces and as an opacifying or coloring agent in ceramic glazes and enamels.
• Mirror Silvering: Serves as a sensitizing agent in the traditional silvering process for manufacturing mirrors and reflective surfaces.
• Textile Industry: Used in dyeing and printing processes as a mordant to improve color fastness of certain dyes on fabrics.
• Water Treatment & Analysis: Applied in specific analytical chemistry methods for the detection and removal of heavy metals and other contaminants.

Quality Control

Our Stannous Chloride is manufactured under stringent quality management systems to ensure batch-to-batch consistency and reliability. We offer various grades, including Technical and High-Purity, tailored to meet specific industry requirements. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles. Our quality commitment ensures the product meets the relevant specifications for its intended use in demanding applications.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature and tendency to be easily oxidized, it is recommended to store the material in a cool, dry, and well-ventilated area under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. The ideal storage temperature range is between 15°C and 25°C. Keep the container tightly sealed when not in use to minimize exposure to air and moisture.
