COATING COMPOSITION WITH ANTI-CORROSION EFFECT Russian patent published in 2018 - IPC C09D5/10 C09D5/08 C09D7/00 C09D163/00 

FIELD: chemistry.

SUBSTANCE: present invention relates to a coating composition with anti-corrosion effect, use thereof for partial coating of a substrate with a primer layer, a method for at least partially coating a metal substrate and a coated metal substrate. Composition includes at least one binder (A), comprising at least one polymeric epoxy resin (A1) and at least one crosslinking agent (A2), having at least amino functional groups, at least one anti-corrosion pigment (B), and at least one organic solvent (C). Pigment (B) is an alloy of Zn and Mg and optionally at least one additional metal and / or semimetal. Coating composition has a volume fraction of pigment (PVC) in the range from 5.0 % to 25.0 %, and includes an anti-corrosion pigment (B) in an amount in the range from 5.0 to 25.0 wt. %, calculated based on the total weight of the coating composition.

EFFECT: invention provides a high anti-corrosion effect and effective adhesion of the coated substrate, respectively, to another, lying on top of the coating.
