Abstract
A method for coating a building panel, the method including applying a first coating fluid including an organic binder on a surface of the building panel to obtain at least one coating layer, and applying barrier components and photocatalytic particles, preferably TiO2, on the at least one coating layer. Also, such a building panel.
Claims8
A building panel comprising a surface, the building panel comprising:
- at least one radiation cured coating layer comprising a organic binder, wherein said at least one coating layer is arranged on said surface, and
- at least one overlying barrier layer comprising barrier components, wherein said at least one overlying barrier layer is arranged on said at least one radiation cured coating layer,
- at least one photocatalytic layer arranged on the overlying barrier layer,
- at least one mixed area comprising barrier components and photocatalytic particles between the overlying barrier layer and the photocatalytic layer, wherein the area is defined by a surface of the overlying barrier layer and a surface of the photocatalytic layer, wherein both surfaces face each other and wherein the overlying barrier layer is uncured when the photocatalytic layer is arranged thereon,
- wherein the polymerized organic binder comprises an acrylate or methacrylate monomer, or an acrylate or methacrylate oligomer.
