FIELD: metallurgy.
SUBSTANCE: electrical steel coating method using lacquer composition for charged core involves application at least of one coating layer of lacquer composition and curing of the applied layer. Lacquer composition for charged core contains 5-95 wt % at least of one alkyd resin with OH nucleophilic groups, 0-70 wt % at least of one polyamid resin containing groups of amide of α-carboxy-β-oxocycloalkylcarboxylic acid, and 5-95 wt % at leas of one organic solvent and/or water. Weight fraction in percents is calculated relative to total weight of the coating composition.
EFFECT: method ensures excellent adhesion and corrosion resistance of coatings, as well as compliance with high-profile standards in combination with various technical requirements.
