  • Patent number: 10414902
    Abstract: An anti-corrosive coating compound with: component I: cathodically active metal particles and component II: binder in the presence of water. In order to improve the service life of the coating compound, it is provided that an oxygen compound or a mixture of oxygen compounds of the subgroup elements, namely ammonium, alkaline or earth alkaline salts of an acid of a transition metal, is added as component III. The invention further relates to a method for producing an anti-corrosive coating compound, a workpiece coated with the anti-corrosive coating compound and the use of an oxygen compound or a mixture of oxygen compounds of the subgroup elements in an anti-corrosive coating compound.

  • Publication number: 20110000793
    Abstract: The invention relates to a coating method for a workpiece, including the following method steps: a) applying a coating liquid to the workpiece, wherein the coating liquid comprises an ionic liquid containing ions of at least one element, b) electrochemically depositing a layer of the at least one element from the coating liquid on the workpiece, c) removing the workpiece from the coating liquid, d) removing excess coating liquid from the workpiece. In order to suggest an industrially suitable coating process, particularly for workpieces having at least a partial metal surface, using stable, durable baths, it is provided that the temperature of the workpiece is set such that the temperature of the coating liquid deviates by no more than 10° C.

  • Publication number: 20060178455
    Abstract: A slip-resistant coating composition comprising (i) a binder comprising a polyepoxide and a polyamine; (ii) a micaceous pigment selected from the group consisting of mica and micaceous iron oxide and blends thereof; (iii) at least one other pigment; wherein the micaceous pigment is present at a level of at least 4% PVC based on total volume solids and wherein the total PVC of the coating is at least 35%. The slip-resistant coating would have a slip coefficient of at least 0.50 after cure and is especially useful in the manufacture of structural joints.
