Stannous Sulphate - White Crystalline Powder, 99.0% Assay As Snso4, Non-hazardous And Electroplating Essential

We offer our clients a quality range of Stannous Sulphate that is widely appreciated in electroplating industry. A method of obtaining stannous sulphate involves a process of electrolysis utilizing a tin anode, and a cathode embodied in material capable both of conducting electricity. Among its various uses, stannous sulphate serves as a coloring agent for aluminum, which acquires a particular bronze-like aspect when treated with the chemical.

UsesStannous Sulphate is a white crystalline product that is a useful source of divalent, or stannous tin (Sn2+).   The most widespread use is in theelectroplating industry and plating baths are maintained under acidic conditions (to prevent precipitation of the tin) with tin contents of approximately 20 grams / litre.The stannous (Sn2+) is an effective reducing agent.  For example, hazardous hexavalent chromium (Cr6+) is converted to non-hazardous trivalent chromium (Cr3+) by reaction with stannous sulphate.  This treatment is of particular importance in the cement / construction industry for the prevention of
