Description
White crystalline, hygroscopic mass. Stannous chloride is used as a mordant for dyeing cellulosic fibers, especially with cochineal, and as a base for lake pigments. Stannous chloride is not used for wools because it makes the fibers brittle. It is also used to galvanize tin and to silver mirrors. Stannous chloride acts as a light sensitizing agent for glass, paper, and plastics.
