Abstract:
A method for producing a hydrophobic or superhydrophobic surface topography on a smooth or structured surface of a pressing tool in the form of a pressing plate, endless belt, or embossing roller for producing material plates, plastic films, separating films, PVC surfaces, and LVTs (luxury vinyl tiles), includes the following steps: preparing a surface template having a microstructure, making an impression of the surface using a resin, scanning the molded surface using a 3-D microscope, converting the digitalized data from the scanning process with depth measurement into grayscale bitmaps, using the grayscale bitmaps to control the machining process of an abrasive surface treatment or to apply a mask for chemically processing the pressing tool in order to produce the surface topography. For this purpose, either the pressing tool is partially covered with a mask and subjected to an etching operation or the determined grayscale bitmap data are used to control an abrasive machining head.
