Studies on the corrosion protection efficiency of alkyd based paint media

Abstract

Mayne and coworkers have carried out intensive studies on the electro‐chemical behaviour of anti‐corrosive paint systems. More recently they have shown that the paint films possess ionogenic sites which become ionised by the absorption of water or moisture and thus become selectively permeable to ions and the process of ion exchange follows. They have also studied the variations in the electrical resistance of a soya alkyd film as a function of the uptake of metallic ions. Bacon et. al. used electrical resistance measurements in assessing the anti‐corrosive properties of some three hundred paint systems, using mild steel panels coated with pigmented paint media as one of the electrodes of the test cell and have shown that the method is quite suitable for predicting their actual performances in marine environments. Khullar and Ulfvarson have determined the ion exchange capacities and ion exchange rates of about twenty different paint media films and drawn a sort of relation between their ionic behaviour and anti‐corrosive abilities.
