COMPOSITION FOR ANTI-CORROSION COATING Russian patent published in 2011 - IPC C23F11/14 C23F15/00 C09D5/08 

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.
