The invention is a coating composition comprising photocatalytic titanium dioxide particles, an opacifying agent, a silicone compound, de-HNOparticles, styrene resin hollow microspheres, and a solvent. The combination of a silicone compound and styrene resin hollow microspheres in a depolluting coating composition results in improved opacity and durability compared to conventional coatings.

Photocatalytically active polysiloxane coating compositions

An improved composition capable of forming a translucent coating on a construction material surface comprising at least:

[object Object]

De-polluting, self-cleaning coating compositions are disclosed which comprise photocatalytic titanium dioxide and a binder comprising an epoxy siloxane polymer. The compositions produce durable, self-cleaning coatings with photocatalytic activity against pollutants in the air, such as NOcompounds.

De-polluting and self-cleaning epoxy siloxane coating

De-polluting, self-cleaning coating compositions are disclosed which comprise an extender that comprises a mixture of calcium carbonate and one or more alternate extenders. The coatings of the invention exhibit improved durability and opacity without affecting the photocatalytic removal of NOcompounds.

Photocatalytic coating compositions

The present invention provides titanium dioxide pigments with improved gloss and/or durability. The titanium dioxide pigments are made by treating titanium dioxide with a plurality of metal salts under conditions suitable to form the titanium dioxide pigment having improved gloss and/or durability, wherein at least one metal salt is capable of providing a monovalent anion. Preferred pigments of the present invention are substantially-sulfate free.
