Abstract

Paint and lacquer coatings (PLCs) are most commonly used when one needs to impart an aesthetic appeal to metal surfaces and protect them from the effects of the environment. Priming paint and lacquer compositions, which are dispersions of anticorrosion pigments in film-forming materials possessing a high adhesion to the surface that is being coated, are rather widespread among the variety of paint and lacquer corrosion- protection materials. The use of a fluorine-containing film-forming material to produce a PLC is rather promising. In this work, we have studied the protective properties of coatings that are based on epoxy varnish and a fluorine-containing polymer and filled with chromate and chromate-free anticorrosion pigments. The protective properties of PLCs have been evaluated by express tests in a salt spray chamber. The PLC structure has been analyzed by scanning-electron and atomic-force microscopy.
