  • the polymer coating has a hardness gradient after curing, so that the hardness of the polymer layer decreases with increasing depth seen from the surface.

  • the present invention also relates to a method for coating a wood-based panel, in particular a floor, ceiling or wall panel, or a wood-based panel is further processed to floor panels, wherein a first liquid coating agent is applied to a wood-based panel in a first step and on the still a first liquid coating agent is applied to wet first coating agents, the liquid layers penetrating each other according to the physics of liquids. This results in a gradient of the concentration of both liquids to each other. While in the outer regions of the total layer (upper side or lower side of the total layer), the respective liquid of the original single layers is dominant, there is a concentration gradient of the first liquid or the second liquid to the middle and further to the other side of the layer.

For example, the layer can be removed stepwise using a Taber Abraser test according to EN 13329.

  • Table 4 Mean values of the sample according to the prior art It has been found experimentally that particularly good mechanical properties of the finished overall layer can be achieved if the hardness gradient of the finished overall layer-as illustrated by way of example in FIG. 3-substantially corresponds to the following relationship:
  • C is the absolute value of the initial hardness in N / mm 2 of the coating at about x ⁇ 0-5 microns depth.
  • the initial hardness value of the coating is the value in the first few microns of the coating. Due to the commonly used measuring method it is difficult to determine the hardness for the penetration depth "0 ⁇ m" by means of a test mandrel which penetrates a few ⁇ m into the coating. The term “substantially” is therefore chosen because it is difficult to achieve a perfectly uniform mixing of the materials. so that it can come in reality again and again to individual small outliers, such as the hardness value of 104.2 Newton / mm 2 at a depth of 42.1 microns (see Table 2) of the example discussed above with hardness gradient. In addition, the values extremely close to the surface of the wood-based panel are generally inaccurate, since the residual layer thickness to be measured must have a certain minimum thickness in order to allow meaningful measurements.
  • the residual layer thickness should therefore be at least 5 ⁇ m, preferably 10 ⁇ m and even more preferably at least 20 ⁇ m, for meaningful measurements.
  • the last 20 ⁇ m of the layer, close to the wood-based panel, does not necessarily have to follow the preferred hardness gradient described above, although this is of course preferred.
  • the hardness gradient essentially follows the following relationship:
  • FIGS. 4 to 6 illustrate the meaning of the above-described relationships of the hardness gradients on the basis of the example with hardness gradient.
  • the given absolute values for hardness and depth are merely exemplary. Of course, it is also possible to apply overall layers with significantly greater thicknesses or lower thicknesses.
  • the absolute value of the hardness of course depends on the materials used and may also be greater or less than the values of the example with Hardness gradient. However, the magnitude of the given values for the hardness gradient example is particularly preferred and suitable for use in a floor panel.
  • the proposed method is particularly suitable for the coating of floor panels, or for the coating of wood-based panels which are further processed to floor panels, since here the beneficial mechanical properties of the hardness gradient most affect.
