Patent ID: 7799432

Claim:
A substrate comprising a biofilm-inhibiting coating, wherein the coating comprises (a) an inorganic condensate that is modified with organic groups, at least a part of the organic groups being fluorine-containing groups selected from one or more of n-C 6 F 13 CH 2 CH 2 , iso-C 3 F 7 OCH 2 CH 2 CH 2 , n-C 8 F 17 CH 2 CH 2 , and n-C 10 F 21 CH 2 CH 2 , a fraction of fluorinated silanes being more than 2.5% by weight, based on all monomers for making the inorganic condensate, (b) at least one of a colloid of copper metal and a colloid of silver metal and (c) nanoscale inorganic particles which are different from a colloid of copper metal and a colloid of silver metal; and wherein the substrate is selected from parts of: land vehicles, watercraft, aircraft, air conditioning plants, heat exchangers, buildings, pipeline systems, satellites, appliances and apparatus for use in food technology, appliances and apparatus for use in drinking-water provision, appliances and apparatus for use in agriculture, appliances and apparatus for use in a kitchen, furniture, outdoor equipment, fences, wooden structures, equipment for process engineering, and equipment for clean-room technology.
