Patent number: 8568834Abstract: A method is provided for preparing on the surface of a substrate a superhydrophilic layer containing at least one metal oxide which method comprises calcining at elevated temperatures a cross-linked precursor film in which film the metal oxide is evenly distributed and immobilized. The precursor film is prepared by sequentially applying to the surface of the substrate a polyamine or other cationic polymer, a suspension of metal oxide and then a suitable cross linking agent. The superhydrophilic layer can be applied as a coating to a variety of substrates including metal, glass and ceramic and provides excellent dirt resistance, scratch resistance and antifogging effect. Multi-layer systems are also available using the inventive process.Type: GrantFiled: January 22, 2009Date of Patent: October 29, 2013Assignee: BASF SEInventors: Valentina Mitina, Michael Chin, Keqing Fa, Thomas Giesenberg
