WATER-BASED COATING COMPOSITIONS Russian patent published in 2017 - IPC C08F289/00 C08F291/00 C09D151/08 C09D191/00 

FIELD: chemistry.

SUBSTANCE: invention relates to coating compositions. Coating composition contains components, obtained using a method which includes: a) reacting epoxidised vegetable oil with material containing hydroxyl functional groups, in presence of an acid catalyst to form a fatty polyol, containing hydroxyl functional groups; b) mixing fatty polyol, containing hydroxyl functional groups, with a functional polyolefin copolymer to form a mixture; c) reacting mixture with ethylenically unsaturated monomeric component in presence of an initiator to form a graft copolymer; and d) cross-linking graft copolymer in presence of a cross-linking agent to form a composition for producing coatings, where graft copolymer or cross-linked graft copolymer is inverted in water. Invention also discloses a method of production and substrates, on which coating is applied.

EFFECT: technical result is coating has high corrosion resistance, resistance to turbidity, to prolonged action of movable medium under pressure, manufacturability during production of articles.
