SOLVENT-CONTAINING COATING COMPOSITION FOR VARNISH COATINGS Russian patent published in 2021 - IPC C09D4/00 C09D5/00 C09D167/08 C09F9/00 

FIELD: building materials.

SUBSTANCE: invention relates to a solvent-containing coating composition for varnish coatings, a coating system containing at least one coating composition, according to the invention, and at least one solvent-containing paste to give a color tone. Besides, the invention relates to coating on substrate obtained by application, as well as physical or chemical drying of the coating composition, according to the invention, or the coating system, according to the invention. The invention also relates to a composite set for the coating system, according to the invention, and to the use of the coating composition, according to the invention, or the coating system, according to the invention, or the composite set, according to the invention, as building varnishes for indoor and/or outdoor works or for obtaining them. The solvent-containing coating composition for varnish coatings contains or consists of: a) at least one organic binder drying as a result of oxidation selected from a group consisting of at least one high-fat alkyd resin drying as a result of oxidation, b) at least one iron-based primary siccative containing or consisting of at least one complex iron salt, c1) at least one first secondary siccative containing or consisting of at least one organic zirconium, strontium, lithium, aluminum salt, e1) at least one first substance for preventing film formation selected from a group consisting of substituted phenols, dialkylaminoethanol, dialkylhydroxylamine, dibenzylhydroxylamine, hydroxylamine, diethylamine, triethylamine and any mixtures thereof, e2) at least one second substance for preventing film formation that at 20°C has higher vapor pressure in comparison with the first substance for preventing film formation and that is ketoxime, f) at least one ligand capable of formation of a complex with iron, d) if necessary, at least one additive.

EFFECT: obtaining solvent-containing coating compositions, drying of which is accompanied with unsignificant release of harmful substances and/or smells, that can be easily applied preferably to various substrates and that are suitable for indoor works.
