    Abstract: This water-repellent, oil-repellent member is obtained via a method comprising: a step for wet-coating a substrate surface with a solution containing an organic silicon compound comprising multiple silanol groups and a solvent; a step for drying the solvent to form a primer layer; a step for wet-coating the primer layer with a solution containing a fluorine-containing compound and a solvent, followed by drying the solvent, or dry-coating with the fluorine-containing compound obtained by evaporating the solvent from the solution; and a step for curing the fluorine-containing compound to form a water-repellent, oil-repellent layer. The water-repellent, oil-repellent member is obtained by providing, on various substrates, a primer layer of a specific thickness containing, as a main component, an organic silicon compound comprising multiple silanol groups, followed by providing, on the primer layer, a water-repellent, oil-repellent layer of a specific thickness containing, as a main component, the cured fluorine-containing compound according to the above mentioned method. It is thus possible to stably and simply form a water-repellent, oil-repellent coating exhibiting superior abrasion resistance on various substrates, and the primer layer and water-repellent, oil-repellent layer can be applied using a room-temperature (25° C.) process.

    Abstract: The present invention relates to a method of treating PVC plates as well as plates and panels manufactured by this method. Further, the invention relates to plates and panels, in particular wall, ceiling or floor panels, comprising a heat-treated carrier plate (12) based on polyvinyl chloride with a density of, for example, 900 to 2,500 kg/m3 and a film (17) applied thereon. The film is a thin PVC-film and comprises a decorative pattern (18) directly printed thereon.
