EARTH AND MUD REPELLENT COATINGS FROM POWDER MATERIAL Russian patent published in 2020 - IPC C09D5/03 C08K5/02 C08K5/49 

FIELD: chemistry.

SUBSTANCE: invention relates to versions of soil and dirt repellent coatings from powder material, containing anionic fluorine-containing surfactants, and a method of producing coatings of this type. Disclosed is a dirt panel comprising a substrate and a coating deposited on said substrate from powder material, formed from a mixture containing a binder comprising a polymer resin, containing at least two functional groups, which substantially does not contain fluorine-substituted hydrocarbon groups; a cross-linking agent which reacts with functional groups of the polymer resin; and a surfactant composition which substantially does not contain solvents and contains an anionic fluorine surfactant. Anionic fluorine surfactant is present in amount of 0.05 to 4 wt % of total weight of coating composition from powder material.

EFFECT: technical result is obtaining dirt-resistant coatings without deterioration of strength of communication with underlying substrate.
