Abstract

The present invention relates to the use of a mixture that is dispersible, redispersible, or soluble in water, or an aqueous composition for protecting substrates from corrosion, wherein the mixture, or the composition, is based on at least one organic polymer that is soluble in water and at least one organosilicon compound. The invention further relates to a mixture that is dispersible, redispersible, or soluble in water, based on at least one organic polymer that is soluble in water and at least one organosilicon compound having at least one Si—O—Si bond and/or at least one Si—Si bond, wherein either the content of the organic polymer soluble in water, based on the sum of the organic polymer soluble in water and of the organosilicon compound, is between about 40 and about 80 wt.-%, or the organosilicon compound is an oligomer mixture of alkyl alkoxy siloxanes, wherein the oligomer mixture contains 50 to 100 wt.-% of alkyl alkoxy siloxanes, and the same have a degree of oligomerization of 2 to 20. The invention further provides a method for the production of mixtures according to the invention and the use thereof.
