摘要
The present invention is directed to a granulate having photocatalytic activity, comprising particles of an inorganic particulate material coated with a photocatalytically active compound for introducing photocatalytic activity into or on building materials. The invention is further related to the manufacture of such a granulate and its use into or on building materials such as cement, concrete, gypsum and/or limestone and water-based coatings or paints for reducing an accumulation and growth of microorganisms and environmental polluting substances on these materials and thus reducing the tendency of fouling, while the brilliance of the color is maintained and the quality of the air is improved.
