Kerstin Motzkat has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8864916
    Abstract: The invention relates to a method and coating agents used in the method which provide good adherence to and good corrosion protection of metal substrates; the coating coating agents are cross-linkable via radical polymerization. Adhesion promoting compounds are present in the conversion layer in a quantity of about 0.01 to 40 weight percent and contain, on average, one reactive unsaturated group and at least one H-active group per molecule.
    Type: Grant
    Filed: November 7, 2008
    Date of Patent: October 21, 2014
    Assignee: Henkel AG & Co. KGaA
    Inventors: Matthias Koch, Kerstin Motzkat
  • Patent number: 7816434
    Abstract: Process for the production on metal or plastic surfaces of thin, hydrolysis-resistant, scratch-resistant and stain-resistant coatings, wherein the coating material can be applied directly to the cleaned metal surface and subsequently cross-linked by high-energy radiation, in particular UV radiation. The substrates can be coated in the form of strip and only subsequently brought into the required external shape. Coated substrates such as these are no longer susceptible to staining by food, cleaning agents or fingerprints and can also be rendered antibacterial. Objects coated in this manner are thus suitable for use in architecture, for interior fittings of buildings, in furniture-making as well as for ornamental applications, and in particular in households, in sanitary applications, in hospitals and in the food-processing and pharmaceutical industries.
