  • Patent number: 11427716
    Abstract: 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.

  • Publication number: 20210346142
    Abstract: A device having a structured coating for adhering to rough, in particular biological, surfaces, includes a carrier layer, wherein a plurality of protrusions is arranged on the carrier layer, which protrusions each comprise at least a shaft having an end face pointing away from the surface, and wherein a further layer is arranged at least on the end face, wherein the layer has a different modulus of elasticity than the protrusion in question. The further layer can also fill the intermediate spaces between the protrusions such that an internal structured coating is produced.

  • Patent number: 10822697
    Abstract: A method for producing metal structures includes an initiator composition comprising a photocatalytic substance being applied to a substrate. A precursor composition that can be reduced to a metal by the photocatalytic activity of the nanodusts is applied to the layer. A structure template is then applied, partially displacing the precursor composition, and then the substrate is illuminated. Structured metal structures are thus generated.
