A method for manufacturing a product comprising a three dimensional surface layer, said method at least comprising the following steps: applying of a water based resin on an underlying surface of the product, wherein said water based resin is at least in part thermocurable; providing a UV-curable liquid onto at least one portion of said water based resin, when said water based resin is liquid or partially cured; curing the water based resin at least by heating; optional UV curing of said UV-curable liquid; optional removing of said UV-curable liquid; and optional pressing of the surface layer and underlaying surface by a pressing device.

Method for manufacturing panels, in which the method includes at least the step of covering (23) one or more side edges (2-3-4-5) of a relevant panel (1), moving the panel (1) with its respective side edge (4) relatively beyond an application device (34), characterized in that the application device (34) includes at least one, and preferably at least two, nozzles (35-36), with at least one nozzle (35) positioned in the plane of the panel when viewed at an angle (A) of less than 90° to the corresponding side edge (4). The invention also relates to a floor panel (1) with a covered side edge (4).

A coated panel comprises at least a substrate (2) and a top layer applied on the substrate (3). The top layer (3) comprises at least a decor layer (4), a translucent or transparent wear layer (5), and optionally a backing layer. The wear layer (5) comprises - and preferably consists of - a thermally cured acrylate resin. Preferably, the thermal curing partially or completely cures the resin, preferably by a thermally initiated radical crosslinking reaction. The top layer comprises a relief.

A method for making a coated paper sheet, wherein the coated paper sheet comprises a paper sheet and a partially cured acrylate coating layer. The partially cured acrylate coating layer is provided for being at least partially cured in a thermal pressing operation. The method comprises the steps of providing a paper sheet; and applying a coating composition onto the paper sheet thereby obtaining a coating layer on the paper sheet. The coating composition comprises at least an acrylate resin, one or more components that comprise free hydroxyl groups, one or more components that comprise free isocyanate groups, and optionally one or more thermoinitiators. The method comprises the step of gelling the coating composition on the paper sheet to a non-viscous state; and such that the acrylate coating layer is a partially cured coating layer.

Board, wherein the board (11) is based on MgO and MgChloride or wherein the board (11) is based on MgO and MgSulphate, characterized in that the board (11) comprises plant fibers.

A decorative panel (12) comprises a decorative top layer (13), a core (14) and a balancing layer (15). The decorative panel (12) is rectangular; and comprises a first pair of opposite edges (20, 21). The edges of the first pair of edges comprises coupling parts provided with locking parts (27, 28). The decorative surface of the decorative panel comprises at least one slot (30) - and preferably a plurality of slots - extending through the decorative top layer (13) into the core (14).

A method for producing boards, wherein raw material (6) is provided and production steps are performed to obtain said boards, with half products formed during said production steps, wherein the productions steps comprise at least the following production steps: -a basic step wherein at least said raw material (6) is transported to a shaping unit (1); -a shaping step, wherein said raw material (6) is formed into plate shaped material to form a plate shaped half product (7); -a sawing step wherein said plate shaped half product (7) is sawn to board shaped half products (8); wherein these board shaped half products (8) are formed into respective boards, wherein, a number of boards is linked to a respective ID tag or comprises a respective ID tag, wherein said ID tags comprise individual data about parameters relating to production steps of said respective boards.

A panel (1) comprising at least a lignocellulose based substrate (2), such as a wood fiber board or a particle board, said substrate (2) comprising an upper surface and a lower surface, and at least one covering layer (3a, 3b) attached to the upper surface or the lower surface, characterized in that said covering layer (3a, 3b) comprises a metal layer (4) and/or is an electrically conductive layer and method to manufacture such panels.

Method for manufacturing decorative panels, comprising at least the following steps: the step (S1) of providing a substrate (2), the step of providing a top layer (3), the step (S3) of providing a top coating (4) above said top layer forming a coated top layer, and subsequently the step (S2) of providing said coated top layer (3) onto said substrate, wherein said method comprises the step (S4) of forming a randomized relief (5), or a relief completely defined by a curing process, onto the uppermost surface of said top coating.

Floor panel for forming a floor covering, wherein this floor panel (1) is at least composed of a substrate (2); wherein the floor panel, on at least one pair of opposite edges (3-4), comprises coupling parts (5-6), which coupling parts allow that two of such floor panels can be coupled to each other by means of a downward movement (M) of one floor panel in respect to the other floor panel; wherein these coupling parts, in the coupled condition of two of such floor panels, form a first locking system, which effects a locking in a first direction (V) perpendicular to the plane of the floor panels, as well as form a second locking system, which effects a locking in a second direction (H) perpendicular to the edges and in the plane of the floor panels.

The process for the production of particle board, MDF board or HDF board comprises the step of recycling particle board material, MDF and/or HDF board material in which recycled chips and/or recycled wood fibers are produced. The process comprises the step in which the particle board material, the MDF and/or HDF board material is wetted, heated and pressurized, wherein this material is kept under pressure and at an elevated temperature for a certain time. The process comprises the step of supplying the recycled chips and/or the recycled wood fibers as base material in a production process of particle board, MDF board or HDF board.
