COMPOSITION FOR PROTECTING CORRODED METAL SURFACES Russian patent published in 2004 - IPC

FIELD: corrosion protection. SUBSTANCE: cold-drying anticorrosive composition contains, wt %: chlorinated polyvinylchloride resin 6.0-9.0, glyphthalic acid 2.5-7.0, epoxide resin (ED-40) 0.8-2.0, chloroparaffin 1.5-4.0, tannin derivative as rust transformer, pigments 5.0-12.0, fillers 7.0-11.0, and organic solvents - the balance. Thus obtained homogenous composition shows elevated penetrating capacity towards corrosion products. EFFECT: increased rust transformation efficiency and increased adhesion to rusty surface resulting in enhanced protection of properties of lacquer surface and enabled applying composition above thicker rust layer. 2 tbl
