FIELD: metallurgy.
SUBSTANCE: composition for anti-corrosion coating includes alkyd varnish, oil soluble inhibitor of corrosion, siccative and organic solvent. Additionally it contains silicon-organic amide of per-fluor-carbonic acid of formula C3F7OCF(CF3)CF2OCF(CF3)CONH(CH2)3Si(OC2H5)3. As oil soluble corrosion inhibitor it contains product of interaction of boric acid, di-ethanol-amine and fat acids of drying vegetable oil at their mole ratio 1:4:2 correspondingly at the following ratio of components, wt %: alkyd varnish 20-30, the said silicon-organic amide of per-fluor-carbonic acid 1-5. Product of interaction of boric acid, di-ethanol-amine and fat acids of drying vegetable oil 1-5, siccative 3-5 and organic solvent to 100.
EFFECT: raised physical-mechanical and water-, oil-, and benzo-proof properties of anticorrosion coating.
