PROTECTIVE COATING COMPOSITION Russian patent published in 2017 - IPC C09D5/00 B82B3/00 

FIELD: chemistry.

SUBSTANCE: invention relates to compositions for coatings, removed by one layer, namely for protection against from weathering, aging, biodegradation of polymer products, unpainted surfaces of wood, metal, painted decorative coatings of wood products and machinery during transportation, and can be used in all industries for preservation during storage in open areas. A composition for protective coating, containing oil ceresin with a specified dropping point, monosubstituted amides of synthetic fatty acids (SFA) fraction C₁₇-C₂₁ of monoethanolamine triborate and water, is described and further comprises nanoclays of the general chemical formula {Mg₃[Si₄O₁₀][OH]₂}•p{[Al,Fe***]₂[Si₄O₁₀][OH]₂}•nH₂O at n:p ratio of 1.0-1.1, and oil ceresin - with a dropping point of 70°C at the following component ratio, wt %: oil ceresin with a dropping point of 70°C - 15.0-25.0, monosubstituted amides of SFA fraction C₁₇-C₂₁ of monoethanolamine triborate - 2.5-9.5, nanoclays of the general chemical formula {Mg₃[Si₄O₁₀][OH]₂}•p{[Al,Fe***]₂[Si₄O₁₀][OH]₂}•nH₂O at n:p ratio of 1.0-1.1 - 1.0-2.0, water - the rest.

EFFECT: increased efficiency of protective coating properties due to improved coating material adhesion to protective surfaces, biocidal properties for various types of moulds and barrier properties of the protective coating material.
