Description of Stannous chloride dihydrate

Tin(II) chloride, also known as stannous chloride, is a white crystalline solid with the formula SnCl2. It forms a stable dihydrate, but aqueous solutions tend to undergo hydrolysis, particularly if hot. SnCl2 is widely used as a reducing agent (in acid solution), and in electrolytic baths for tin-plating. Tin(II) chloride should not be confused with the other chloride of tin; tin(IV) chloride or stannic chloride (SnCl4).

What’s the application of Stannous chloride dihydrate?

  1. Used as reducing agent, mordant, decolorizing agent, used for tin plating in the electroplating industry
  2. Used for colorimetric determination of silver, lead, arsenic, molybdenum, etc., also used as reducing agent and mordant
  3. Mainly used in acid tin plating, as the main salt. Tin in the plating solution is the divalent state, high cathodic efficiency, the general dosage of 40 ~ 60 kg / L. Can also be used in the glass mirror industry, as a silver nitrate plating sensitizer, so that the brightness of the coating is good, in ABS plating when adding this product plating is not easy to fall off
  4. Used as a reducing agent in the manufacture of dye intermediates. Used as a component of ultra-high pressure lubricating oil. Used as the bleaching agent. Used for the sensitization treatment of mercury plating in mirror making, the silver film formed has good brightness, and the mercury is firmly combined with the product. Used in the electroplating industry for tin plating and copper plating of mechanical parts. In ABS plastic plating is used for sensitization Chemicalbook treatment so that the plating layer is not easy to fall off. It is also used in the synthesis of pharmaceuticals, a catalyst of organic synthesis, and an activator of vulcanization of butyl rubber products. It is used as a mordant in dyeing and as an anti-dyeing agent in the printing and dyeing process. Stabilizer for spice industry. Food reducing agents, antioxidant, such as asparagus cans, pineapple juice.

Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.

In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!

Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
