Biocidal roofing granules are prepared by providing a mineral core and at least one biocidal photocatalytic metal oxide. A gel-forming inorganic coating medium is prepared and used to coat the mineral core to form a coating layer having a porous network on the mineral core, and the at least one biocidal photocatalytic metal oxide is disposed in the porous network.

Biocidal roofing granules, roofing products including such granules, and process for preparing same

The invention relates to biocidal granules composed of a mineral core coated with at least one porous inorganic layer including at least one organic compound capable of limiting or preventing the growth of microorganisms, in particular of algae. The invention also relates to a sol-gel process for the preparation of the biocidal granules and to the use of these biocidal granules in building materials, in particular shingles and siding coatings.

Biocidal granule, in particular for making asphalt shingle

The invention relates to a substrate comprising at least one photocatalytic compound active under the conditions of illuminating an interior of a building or transport vehicle, intended to neutralize the microorganisms with which it comes into contact, and also to its preparation processes and its uses as glazing or another substrate for disinfection, filtration, ventilation, etc.
