Abstract: 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.

Abstract: The invention relates to a method for producing a silane-modified silicate. In order to obtain optimal corrosion protection properties, a silane compound according to the invention is at least partially hydrolyzed and/or condensed in the presence of a silicate compound at a pH value greater than or equal to 8 and then a pH value less than or equal to 7 is set by adding acid. The invention further relates to an aqueous acidic passivation composition for metal substrate coated with the passivation composition.
