VARNISH-PAINT COMPOSITION FOR OBTAINING THIN COATINGS BY CATHODIC ELECTRODEPOSITION METHOD

摘要

The invention relates to aqueous varnish-paint compositions having a high dispersibility which are used to obtain chemical-resistant and heat-resistant coatings by a cathodic electrodeposition method. The technical result of the invention is increased heat resistance, salt resistance and water resistance of the coating as well as high chemical resistance of the coating. A varnish-paint composition for obtaining thin coatings by a cathodic electrodeposition method comprises an aqueous emulsion of epoxy resin comprising a concentration of 36-38% by reference standard, 100% acetic acid, 2% aqueous solution of 3-(aminopropyl)triethoxysilane and demineralized water, having the following component ratio, g/l: 120-150 of aqueous emulsion of epoxy resin; 0.1-0.6 of 100% acetic acid; 5-50 of 2% aqueous solution of (3-aminopropyl)triethoxysilane; up to 1 l of demineralised water for the remainder.
