ANTICORROSION COMPOSITION BEING APPLIED ON SURFACE WHICH IS NOT PURIFIED AGAINST LAYER OF RUST Russian patent published in 1997 - IPC

FIELD: protection against corrosion. SUBSTANCE: proposed composition contains (%): vat residue of synthetic fatty acids 81-89, unslaked lime 4-10, side product of production of caprolactam 4-1. Into melt of said synthetic fatty acids initially is added said side product, then unslaked lime. The process takes place at 70-80^°C. Then temperature is brought to 180-190^°C and mixture is mixed till homogeneous mass is prepared. Density thus prepared composition is 1.29-1.32 g/cm³.. EFFECT: increased service life of metal constructions, decreased cost of composition. 2 cl, 3 tbl
