Abstract RU 2738655 C2

FIELD: chemistry.

SUBSTANCE: invention can be used for covering facades of buildings or walls of internal premises of buildings. Coating composition contains at least one organic binder comprising copolymers of vinyl acetate with ethylene, copolymers based on vinyl aromatic compounds and acrylates or copolymers based on pure acrylates, liquid glass, kieselsol, at least one first filler and/or at least one first pigment with particle size D50 less than or equal to 2.0 mcm. At that, mass fraction of dry substance of kieselsol is higher, than weight fraction of dry substance of liquid glass, in conversion in each separate case to total weight of dry substance of coating composition. Disclosed also is a coating obtained from said composition and use of the coating composition to obtain a coating on the surface of the substrate.

EFFECT: invention enables to obtain silky-lustrous or glossy coatings, characterized by high resistance to wet abrasion, using a storage-stable composition which does not contain preserving agents.
