Why is Titanium Dioxide (TiO2) used in paints?

In paints, titanium dioxide (chem. TiO₂) is mainly used as a white pigment. Only micrometre sized titanium dioxide causes such white colouring. Nanoscale titanium dioxide functions as UV filter protecting the paints’ binder material. Equally, it degrades organic materials via generation of radicals (photocatalytic actovoty ), which is e.g. used for self-cleaning surfaces.
