摘要: Abstract This study is focussed on the use of organic phosphorous compounds for improvement corrosion protection a carbon steel by UV-cured polyurethane coating. Two were employed: one with long hydrocarbon chain: tridecylphosphate (TDP) and second an unsaturated methacryloxyethylphosphate (MOP). The used either surface treatments before application coating or added directly to Corrosion resistance coated was evaluated electrochemical impedance spectroscopy. For treatment, treatment time optimised mixture 5% TDP+1.5% MOP. A 60 min led best protection. By incorporating into coating, it shown that TDP alone significantly improved protective properties.
