The present invention relates to modified-metal -particles for corrosion-protection coatings 16 a method for their production and their use anti-corrosive coating compositions and methods for their use. The coating compositions include modified metal particles and a binding agent. The modified metal particles can include zino, aluminum, magnesium, bismuth, tin, nickel, or manganese as well as their mixtures and alloys thereof and have an inorganically-based surface modification in the form of a coating layer capable of imparting cathodic corrosion protection. Suitable surface modifications include a coating layer formed by an inorganic oxide including silicon dioxide, titanium oxide, zirconium oxide, and mixtures thereof.

Corrosion protection pigment comprising coated metal particles and its use

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.

Anti-corrosive coating compound

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.

Anticorrosive coating composition

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.
