  • Anti-corrosive coating compound
    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.
    Type: Grant

  • Anticorrosive coating composition
    Patent number: 10308819
    Abstract: The invention relates to an anticorrosive coating composition. In order to provide an anticorrosive coating composition which cures at room temperature, provision is made for the anticorrosive coating composition to comprise at least one polysiloxane and metal particles and also at least one crosslinker, the coating composition crosslinking chemically at room temperature. The invention further relates to a method for applying the anticorrosive coating composition and also to the coated substrate.

  • Method for the manufacture of a substrate provided with a chromium VI-free and cobalt-free passivation
    Patent number: 10011907
    Abstract: A method for the manufacture of a substrate provided with a chromium VI-free and a cobalt-free passivation by the application of a first acidic passivation and a second alkaline passivation, containing a silane-modified and/or a siloxane modified silicate, with which an improved protection against corrosion is achieved, an aqueous, acidic composition for passivating and a passivated substrate, and a device for applying the passivation.
