Stannous chloride dihydrate

Stannous chloride dihydrate is a white or colorless crystal, used for the colorimetric determination of silver, lead, arsenic, molybdenum, etc. It is also used as a reducing agent, mordant use as strong reducing agent, used for hydride determination by AAS, colorimetric determination of silver, lead, arsenic, molybdenum, determination of inorganic phosphorus and alkaline phosphates enzyme activity in serum, molybdenum blue method of determining the phosphorus content of the soil and the plant, and the catalyst for organic reaction. Stannous chloride dihydrate is mainly used in acid tin plating, as the main salt. Tin is bivalent in the plating solution, high cathodic efficiency, general dosage of 40-60kg/L. It can also be used in the glass mirror industry, as a sensitizer for silver nitrate plating, so that the brightness of the coating is good, and it is not easy to come off the plating layer in ABS plating with the addition of this product. Stannous chloride can be used as reducing agent for dye intermediates. It is also used as a component of ultra-high-pressure lubricating oil. Used as bleaching agent. Used in the sensitization treatment of mercury plating in mirror making, the silver film formed is of good brightness, so that the mercury is firmly combined with the products. Used in electroplating industry for tin plating and copper tin plating of mechanical parts. It is used for sensitizing treatment in ABS plastic plating, so that the plating layer is not easy to come off. It is also used in the synthesis of pharmaceuticals, catalyst for organic synthesis, activator for vulcanization of butyl rubber products. Mordant in dyeing and anti-dyeing agent in printing and dyeing process. Stabilizer in spice industry. Food reducing agent, antioxidant, such as canned asparagus, pineapple juice.
