[Abstract] New low cost masking coatings have been developed. These coatings are based on corrosion resistant polyurethane and acrylic-urethane priming varnishes and paints of Ukrainian manufacture (InterGasSinthez). In addition, the coatings are also based on nanopowders of polyvalent iron oxides obtained by electroerosion dispersion [1], carbon, omega spheres (based on silica and alumina), and basalt fibers demonstrating high absorption abilities (90-99%) of microwaves in a wide range of frequencies (10-70 GHz, wavelength 0,03-0,0043 m) with their reflection close to zero (-10 Db - - 23 Db or 10% -0.5%). Polymeric bases of the developed coatings are used to protect against corrosion of metal structures in all macroclimatic areas, in sea and fresh water, in saline solutions, and in oil and oil products that are resistant to ultraviolet radiation, aggressive media. They demonstrate high mechanical performance (adhesion, strength, elasticity) and long service life. The coatings can be used for painting of ships, deck structures, containers, building constructions and buildings, auto and railway transports, parts and mechanisms, etc.
