This invention relates to a photocatalytic paint with an antibacterial and antipollutant effect, designed for use in residential and public buildings, which contains a percentage of an element with photocatalytic activity, in particular a mixture of titanium dioxides in the form of anatase that promotes oxidation-reduction reactions of the pollutants present in the air. In particular it relates to a paint in which the mixture of titanium dioxides chosen has a particle size such that it has a high specific surface area, and which contains a suitable quantity of potassium silicate instead of the common organic binders normally used in paint.
The result is a paint which does not deteriorate with time, and which contains a compound able to eliminate the pollutants present in the air and prevent the blackening characteristic of exposed surfaces.
