PRIMING-ENAMEL OF AQUEOUS DISPERSION ANTI-CORROSIVE SERIES "KRONAKRIL"

FIELD: paint and varnish materials. ^ SUBSTANCE: invention relates to priming aqueous-dispersion compositions designated for protection metallic surfaces against corrosion in exploitation both under atmosphere conditions and subjected for effect of different liquids. Invention proposes anti-corrosive aqueous-dispersion priming-enamel comprising the following components, wt.-%: styrene-acrylic dispersion as a binding agent, 30-50; calcium molybdate phosphate as an anti-corrosive pigment in the following ratio of molybdate and phosphate ions from 1:0.01 to 1:100; color-forming pigment, 1-10; phosphate dispersing agent, 0.1-10; thickening agent, 0.05-0.2, and water, the balance. Applying calcium molybdate phosphate in priming-enamels provides the passivating activity in interaction 0f phosphate-molybdate ions with metallic backing of both ferrous and nonferrous metals and exhibits the additional protecting effect. ^ EFFECT: improved and valuable properties of compositions. ^ 2 tbl
