| Chemical Properties | Back Directory | [Description]
TBTO (bis(tri-n-butyltin)oxide) appears as thin, colourless to pale yellow, flammable and
combustible liquid. It is soluble in organic solvents. TBTO, or bis(tri-n-butyltin)oxide, is an
organotin compound used as a biocide, fungicide, and molluscicide. Uses of tributyltin also
include as an anti-fouling chemical in marine paints for boats, anti-fungal agent in textiles
and industrial water systems, in cooling tower and refrigeration water systems, wood pulp
preservative in paints and paper mill systems, inner surfaces of cardboard, and in the manufacturing
processes of leather goods, textiles, wood, plastics, and mothproof stored garments.
In fact, TBT compounds are considered the most hazardous of all tin compounds. | [Appearance]
