In article test results of coatings on the basis of the organic silicon varnish modified by
organosilazanes are provided. Influence of the different elements entered into structure of the modifying
additive on basis oligorganosilazanes, on properties of coatings is shown.

The article is devoted to the developed domestic system of coatings «base coat/clear coat» type, intended for protective and decorative painting of the external surface of aircraft. The system includes base enamel of the VE-84 trademark in a wide range of colors and weather-resistant varnish of the VL-25 trademark for the outer layer, which has high resistance to UV radiation, the ability to maintain gloss for a long time and provides protection of coatings from color changes. The article presents the results of accelerated corrosion and climatic tests, dielectric, physical-mechanical and operational indicators.

The characteristics of aniline polymerization product from the point of view of its use as an inhibiting component of paint and varnish coatings are considered. The influence of doping and synergic combinations with other inhibitors on realization of anticorrosion potential of polyaniline is noted. The prospects of application of nanosized core polyaniline pigments are pointed out. of accelerated corrosion and climatic tests, dielectric, physical-mechanical and operational indicators.
