FIELD: metallurgy.
SUBSTANCE: invention relates to chemical treatment of surfaces of ferrous metals before painting and can be used for protection of metal structures from corrosion by zinc silicate paints and primers. Composition for chemical treatment of surface of ferrous metals before painting with zinc silicate compositions contains following components, wt%: phosphoric acid (p = 1.8 g/cm3) 40–50, glycerol 10–15, talc or kaolin 30–35, sodium chloride 0.5–1.0, zinc chloride 0.05–0.10, water – balance.
EFFECT: higher quality of treated surface, providing high physical and chemical characteristics of zinc silicate coating, such as adhesion, water resistance and others.
