Abstract
The presence of soluble salts at the substrate/coating interface can lead to the premature deterioration of organic coatings. Industry and marine atmospheres, pretreatment with contaminated abrasives and de-icing salts are main sources to contaminate substrates. In this paper, the effects of soluble salts on coating performance are studied. The analyzing methods of type and quantity of salts and also the methods for removing soluble salts are described. In addition, permissible level of soluble salts for different coatings is explained.
