FIELD: paint and varnish industry, anti-corrosive agents.
SUBSTANCE: invention relates to corrosion modifying agents used for covering metallic surfaces without their preliminary cleansing from corrosion products. The corrosion modifying agent comprises the following components, wt.-%: hydrolysis lignin, 19-23; oil as by-side product in caprolactam manufacturing, 5-10; thermic ortho-phosphoric acid in the concentration 70%, 17-26, and water, balance. Invention provides preparing a composition transforming rust corrosion with layer thickness up to 160 mcm that provides enhancing adhesion of applied paint and varnish materials after treatment with the proposed modifying agent significantly.
EFFECT: improved and valuable properties of agent.
