Molecular formula: K₂SnO₃•3H₂O Molecular weight: 298.60

white crystal, white powder or colorless crystal.

Uses: Electroplating industry (especially in the tin plating of electronics, automobile manufacturing, canned food, etc.) and fabric dyeing and printing industry, also used in glass, ceramics lamp industry. In alkaline tin plating solution, it can produce higher cathodic efficiency and conductivity than other tin salts, and improve the surface brightness, adhesion and corrosion resistance. It can be used in the electroplating of automobile, electronic industry, food, and canned food. Also can be used in mordant, etc.
