FIELD: chemistry.

SUBSTANCE: invention relates to the protective coating that is applied as corrosion protection coatings for corrosive bases, particularly corrosive metals, alloys, and other materials, in particular steel, used as a primer coating for causing further multi-layer porous coatings or as a surface layer, as well as to the method in which it is received and the application on the coated base for the corrosion protection, in particular, for the use against microbiologically induced corrosion (MIC). An anticorrosion coating has a thickness of at least 50 μm. The anticorrosion coating includes a high-density protective coating of the base subject to corrosion, containing the pre-condensed precursors of alkoxysilane forming a coating. The molecules of the pre-condensed precursors of alkoxysilane forming a coating are constructed by linear and short-chain ones from the monomer units from the group of precursors of alkoxysilane. Moreover, the molecules of the pre-condensed precursor of alkoxysilane forming a coating are cross-linked. Obtaining anticorrosive coating involves preparing the anticorrosive composition, in which at least one precursor of alkoxysilane forming a coating without a solvent and additives by adding water in a molar ratio of 3:1 to 1:1 under acidic pH conditions, at a temperature in the range of 0°C to 10°C is converted into a pre-condensed precursor of alkoxysilane forming a coating. Further, the anticorrosive composition is applied to the substrate and cured to produce a high-density protective coating.

EFFECT: production of high-density anticorrosion coating, suitable for corrosion protection, including for protection against microbiological corrosion of various materials.
