ABSTRACT:
A process for producing deformable acrylic panels with increased resistance to abrasion and scratching preferably for sanitary articles to be produced by the deep-drawing process. Immediately prior to the deep-drawing step, a type of lacquer is applied to an acrylic panel. The lacquer contains dispersed nanoscale particles preferable of an inorganic material. The semifinished acrylic panel is heated and subsequently deep-drawn. The lacquer coating is applied to the semifinished acrylic panel with the help of rollers or a doctor blade. In addition, the lacquer coating can be applied by immersing or flooding the semifinished acrylic panel.
