Abstract

The invention relates to a coating material comprising a binding agent, at least one filler containing particles having a size and/or surface roughness of 100 pm or less, and a photocatalytically active agent. According to the invention, the binding agent is at least partially decomposed by a photocatalytic action, and a microstructured, self-cleaning surface is formed.

Claims (14)

1. Coating material for the coating of facades and other building surfaces, comprising a binding agent and at least one filler containing particles having a size and/or surface roughness of 10 µm or less, preferably 1 µm or less, specifically 0.1 µm or less, as well as a photocatalytically active agent, characterized in that the binding agent is capable of being decomposed, at least partially, by the photocatalytic action of the photocatalytically active agent in such a way that the photocatalytic decomposition is equivalent or less than chalking level 1 as per DIN EN ISO 4628-6, and so that a microstructured, self-cleaning surface is created by the photocatalytic reduction of the layer thickness of an external coating, formed by the coating material, by 0.1 µm or more, preferably 1 µm or more, per year, given external weathering as per EN ISO 2810 (Klima Da, Probenkörper vertikal and derv Äquator zugewandt [Sample vertical and oriented in the direction of the equator]).
2. Coating material in accordance with claim 1, characterized in that the binding agent is at least partially photocatalytically degradable and the catalytically active agent has at least one photocatalytically active metal oxide.
3. Coating material in accordance with claim 1 or 2, characterized in that the binding agent exhibits an aqueous polymer dispersion, a polymer dispersion capable of being redispersed in water, a hydrophobic resin and/or a preliminary resin product or so-called nano composite.
4. Coating material in accordance with any of the preceding claims, characterized in that the binding agent contains silicone or silicate.
