An anti-corrosion coating to protect against corrosion, comprising: a high-density protective coating on a substrate which is prone to corrosion, preferably metals and/or alloys thereof, containing pre-condensed coat-forming alkoxysilane precursors, wherein the molecules of the pre-condensed coat-forming alkoxysilane precursors are built up from monomer units selected from the group formed by coat-forming alkoxysilane precursors, wherein the molecules of the pre-condensed coat-forming alkoxysilane precursors are cross-linked with each other, wherein the high-density protective coating has a coating thickness of at least 50 &#x3bc;m. The high-density protective coating formed by an inorganic-organic hybrid material, which is preferably produced without solvents (i.e. without the addition of solvents, in particular organic solvents), is comprised of at least one coat-forming alkoxysilane precursor, in particular selected from the group formed by trialkoxysilane precursors.

Anticorrosion layer and process for production thereof

The invention relates to a protection layer which is used as anticorrosion layer on corrosion-prone substrates, especially corroding metals, alloys and other materials, especially on steel, and as a basecoat for the application of further porous layer systems or as a topcoat, and to the process for production thereof and to use on a coated substrate for protection against corrosion and specifically for use against microbially induced corrosion (MIC), wherein the anticorrosion layer comprises a high-density protection layer on a corrosion-prone substrate, containing pre-condensed layer-forming alkoxysilane precursors, wherein the molecules of the pre-condensed layer-forming alkoxysilane precursors are formed from monomer units selected from the group of the triethoxysilane precursors, wherein the molecules of the pre-condensed layer-forming alkoxysilane precursors are crosslinked with one another, and wherein the high-density protection layer has a layer thickness of at least 50 &#x3bc;m.

There is provided herein a method of preparing an isocyanatosilane including reacting an olefinic isocyanate with a hydridosilane in the presence of a dinuclear rhodium complex under hydrosilylation conditions.
