Abstract
A method for coating of a floor panel and a floor panel produced by the method. A method for producing a laminated product, for example a building panel, preferably a floor panel. The method includes applying a paper on one side of a wood fiber based core, e.g., an HDF panel, creating a décor on the paper by a digital printing process, applying a resin, preferably a melamine formaldehyde resin, on the paper, heating the décor and the paper with the resin, preferably by using an IR lamp; and applying heat and pressure in order to cure the resin and thereby obtain a laminated product. Also, alternative methods for producing a laminated product, and such a laminated product.
Claims19
A method for producing a laminated product, the method comprising:
- applying a powder-based sublayer comprising wood fibers and a thermosetting resin on a wood fiber based core;
- applying a paper on the powder-based sublayer, wherein the paper is an unimpregnated paper when the paper is applied on the sublayer;
- applying a protective overlay comprising a thermosetting resin and wear-resistant particles on the paper;
- and
- applying heat and pressure in order to impregnate the paper, to cure the resins, and thereby obtain a laminated product.
