FIELD: construction.
SUBSTANCE: composition for producing protective coatings contains in pts. wt.: polyurethane prepolymer 100, polymethylphenylsiloxane 10-60, fine-grained electroformed mud 20-50, pigment 0.01-5. A technical result of use of this composition is the monolithic coating filled with electroformed mud, capable to penetrate inside the surface to be protected, having high adhesion to the surface, low moisture permeability, self-extinguishing effect. The coating is self-extinguishing after exposure to open flame (combustion up to 8 seconds).
EFFECT: increase in the hardness of the cured coating.
