Abstract:
1. Anti-corrosive coating composition including an aqueous, film forming, polymeric siloxane produced from at least one of the group consisting of alkyl- or alkenyl silanes, methacrylic silanes and silanes which contain epoxy-, mercaptane- or hydroxyethyl groups, then coating composition having a pH-value between 3 and 5, the coating composition further comprising particles enveloped by the siloxane, said particles being selected from the group consisting of aluminium, yttrium, niobium, cerium or lanthanium compounds and mixtures thereof, and nano-tubes, carbon black or intrinsic conductive polymers, said coating composition for coating of metal surfaces including at least one further additive, said additive being at least one particulate metal for the improvement of the corrosion properties of the metal surface to be coated, said additive being added in an amount of from 10 weight % up to 95 weight % based on the overall formulation of the coating composition, wherein during curing the coating composition liberates less than 5% by weight alcohols based on the overall amount of the coating composition.
