Tributyltin compounds are usually clear to yellowish liquids with an unpleasant odor.
Triphenyltincompounds are white solids with low vapour pressures. Tri-organotin
compounds are derivatives of tetravalent tin. They are lipophilic and have low water
solubility. Physical and chemical properties of tri-organotin compounds vary depending
upon the anion linked to tin. Tributyltin derivatives have toxic properties to gram positive
bacteria are used as disinfectants on surfaces such as hospital floors and sports
arenas, combined with gram negative bactericides. Tin chemicals also used as flame
retardants to treat fabrics and plastics. Tributyltin methacrylate is used as a stabiliser for
PVC. Other industrial applications of organotin compounds include as rodent repellents,
antioxidants, curing agents and corrosion inhibitors.
Sodium stannate is used as a salt in alkaline tin plating electrolyte. It is used in surface
coatings (paper). It is used in manufacturing other metallic stannates and tin oxide
coatings.
