FIELD: chemistry.
SUBSTANCE: invention relates to protective anti-corrosion coatings based on polyorganosiloxanes and is intended for heat insulation and anti-corrosion protection of metal structures. The protective coating composition includes organosilicon polymer binder, metal oxides, aerosil, a silicate, tetraethoxysilane and an organic solvent - o-xylene. The silicate is micromica, microwollastonite and microtalc; the organosilicon polymer binder is polymethylsiloxane resin or polymethylphenylsiloxane resin, or a mixture thereof, or organosilicon lacquer based on polydimethylphenylsiloxane resin.
EFFECT: coating based on the disclosed composition is a natural drying coating, has good physical-mechanical properties with low content of filler in the composition.
