PHOTOCATALYTIC COMPOSITIONS AND THEIR APPLICATION FOR PRODUCING WATER PAINTS

摘要

The invention relates to photocatalytic compositions, e.g. cement-based photocatalytic compositions, and the uses thereof for obtaining water paints. There is provided a photocatalytic composition, which comprises: (a) at least one inorganic binder; (b) at least one photocatalyst; (c) at least one cellulose with very low viscosity; (d) at least one fluidizing agent; (e) at least one first calcareous filler in the form of particles of which at least 95% by weight has a dimension not greater than 40 μm; (f) at least one second calcareous filler in the form of particles of which at least 95% by weight has a dimension not greater than 20 μm; (g) at least one thermal insulator material comprising hollow ceramic spheres with sub-mm diameters, and (h) glass bubble borosilicate microspheres.
