METHOD FOR APPLYING ANTI-CORROSIVE LAYER TO METALLIC SURFACE AND COMPOSITION FOR ANTI-CORROSIVE LAYER Russian patent published in 2005 - IPC

Abstract RU 2252978 C1

FIELD: corrosion prevention technologies.

SUBSTANCE: method includes serial application of layers of polymer compositions to metallic surface, while serial layers of polymer compositions are made with various thermal expansion coefficients. As said polymer composition polyurethane compound is used with special admixtures and filling agent, influencing thermal expansion coefficient of covering layer, and content of said filling agent in each following layer is set less than content of said filling agent in previous layer.

EFFECT: higher efficiency.
