Definitions
- the invention relates to a method for the surface design of sanitary fittings, different areas of the surface of the finished sanitary fitting being coated or varnished differently, and wherein the basic body of the sanitary fitting preferably has a metallic surface in which the points of interest on the basic body are made accessible and the remaining surface is or remains protected, in which case the surface as a whole is subjected to a coating or painting step in which the coating or painting does not adhere to the protected areas of the surface or together with a layer protecting these areas is removed and finally the surface additionally coated or lacquered at the points of interest is subjected to a total finishing - polishing, protective lacquer application.
- the manufacturing process for sanitary fittings which has been explained above, is expensive, so that the object of the invention is to provide a manufacturing process which is more cost-effective with the same result.
- the above-mentioned object is achieved in that a positive photoresist is applied over the entire surface of the base body, that the photoresist surface is exposed at the points of interest, in particular UV-exposed, that the photoresist surface, in particular with a liquid developer developed, and thereby or thereafter at the UV-exposed point of the photoresist is removed and that then the surface of the loading . undergoes layering or painting step.
- positive photo varnish ie photoresist, which after exposure, in particular exposure by means of a UV source, is prepared in such a way that it can subsequently be attacked by the developing agent and removed from the surface.
- Photoresist is also available in the form of negative photoresist and then gi that a negative photoresist is applied over the entire surface of the base body, that the photoresist surface is covered at the points of interest and otherwise exposed, in particular UV-exposed, that the photoresist surface is developed, in particular with a liquid developing agent, and the photoresist is removed in the process or thereafter at the non-UV-exposed areas and the surface is then subjected to the coating or painting step.
- the surface layer applied in the coating step is a chrome layer, another metallic surface layer or a lacquer layer.
- a particularly preferred area of application for the present process technology is, however, the galvanic gold plating of the points of interest.
