| 摘要 |
<p>The invention relates to a substrate having at least one decor layer or overlay being applied to at least one surface of the substrate, wherein hard particles are distributed over the decor layer or overlay for improving the abrasion resistance of the decor layer or overlay, wherein the hard particles have a coating containing a silane, preferably an aminosilane, providing a chargeable or electrically conductive surface for the coated particles. Furthermore, the invention relates to a process for the distribution of hard particles on a décor layer or overlay applicable to a substrate, comprising the steps of applying a thermosetting resin to the decor layer or overlay, providing hard particles having a coating containing a silane, preferably an aminosilane, providing a chargeable or electrically conductive surface for the coated particles, evenly distributing the coated particles on the surface of a feeding device, distributing the coated particles on the decor layer or overlay by releasing the evenly distributed particles from the feeding device by use of an electric field applied to the feeding device and coated particles thereon, and drying or curing the thermosetting resin.</p> |
