Sodium stannate Typical Properties

Sodium stannate Usage

• lkaline Tin & Alloy Electroplating (Core Industrial Application): Serves as the premier alkaline electroplating salt across modern metal finishing industries.

  • Electrotinning & Alloy Deposition: Widely used for the continuous tin plating of electronic components, copper strips, and steel sheets; it offers excellent throwing power (uniformity of plating) and produces dense coatings that are resistant to dendritic crystal formation.

• Textile & Dyeing Industry (Mordant & Weighting Agent): Utilized as an effective mordant in cotton and silk printing/dyeing; functions as a fabric weighting agent and flame retardant in silk processing.

• Hydrogen Peroxide Stabilizer: Added in trace amounts to industrial hydrogen peroxide (H2O2) matrix to sequester catalytic heavy metal impurities, preventing hazardous peroxide decomposition during storage.

• Specialty Catalysts & Glass Surface Treatment: Handled as a precursor for tin-based chemical catalysts, ceramic pigments, and hot-end glass container coatings to improve mechanical impact resistance.
