Patent number: 11427716Abstract: A highly structured composite material, which can be applied and cured as a protective layer on corroding metal substrates, particularly on steel is provided. Due to its highly structured composition it is a particularly effective barrier to protect metals against attack by corrosive substances such as hydrogen sulfide, carbon dioxide and sea water, if necessary under hydrothermal conditions. At the same time it is also abrasion stable, for example against a grinding effect by sand, as well as resistant to the impact of mechanical load e.g. by tools. This is achieved by a coating composition comprising a binder comprising at least one cross-linkable resin, wherein the resin comprises at least one of polar group; at least one type of hydrophilic flakes with an aspect ratio of more than 10, wherein the surface of the flakes at least partially comprises a metal oxide; and an organic solvent.Type: GrantFiled: December 20, 2012Date of Patent: August 30, 2022Assignee: Leibniz-Institut für Neue Materialien gemeinnützige GmbHInventors: Carsten Becker-Willinger, Frank Hollmann, Marlon Jochum, Michael Opsoelder, Sabine Schmitz-Stoewe, Douglas Espin
