This article is devoted to the research of lignin influence on structural and mechanical properties of paint and varnish coverings in a complex with the lignin corrosion modifier, mostly defining their adhesive stability on metals Fe₂O₃ and Fe₃O₄. In the result of research it was proved that molecules of the lignin containing surface-active substances not only shield separate sections of metal, but also create the power barrier existing even at a partial covering of a surface, interfering penetration of aggressive components of the environment through the adsorptive layer of surfactant molecules. The result of the research allows reviewing more accurately the mechanism of anticorrosive activity of lignin modifiers of corrosion products.
