ANTICORROSIVE COATING COMPOSITION Russian patent published in 2020 - IPC C09D5/08 C09D7/00 C09D163/00 

FIELD: chemistry.

SUBSTANCE: disclosed solution relates to coating compositions with anticorrosive effect, particularly to two-component compositions based on epoxy resins and curing agent. Anti-corrosion coating composition contains a base containing a binder which is a mixture of polyvinyl chloride chlorinated resin with epoxy-diane resin, a mixture of solvents, pigment mixture containing at least one anticorrosive pigment and corrosion inhibitor, filler, plasticiser, thickener and dispersant. Composition additionally contains a phenalkynic curing agent, and the anticorrosive pigment is zinc phosphate. In a preferable version epoxy-diane resin is epoxy-diane E-40 resin 80%, and mixture of solvents contains acetone, butyl acetate and xylene at the following ratio, wt% to total weight of composition: acetone 17-18, butylacetate 12-13 and xylene 25-26. Filler used is talc; the plasticiser used is chloroparaffin.

EFFECT: technical result consists in creating a composition for anticorrosive coating, characterized by a wide temperature range of use, possibility of application on wet surfaces, without need to observe the dew point.
