The main industrial application of Tin dichloride dihydrate is in catalysts, metal surface treatment and as mordant for textile dyeing. Tin chloride is used in laboratory chemicals, inks and toners and also textile treatment products and dyes. Tin dichloride dihydrate is also employed as a reducing agent in the production of pigments, pharmaceuticals, sensitized paper, lubricating oil additives, organic and inorganic chemicals. Dichlorotin is also used in tinning (by means of galvanic method) and in sensitizing of glass, plastics, and other non-conductive surfaces. Tin dichloride dihydrate is used by many companies as a soldering flux, as a chemical reagent, as an organic catalyst and - in some cases - as food additive. Tin dichloride dihydrate is also used as a reducing agent to produce polymers and phosphors and also to stabilize perfumes in soaps.
