Abstract

This book outlines issues involved in the protection of metallic corrosion using paints and inhibitors. The barrier performance of paints against corrosive elements of the environment depends on properties like ionic resistivity, water uptake and oxygen diffusivity through the polymers and adhesion. The roles of these properties against corrosion are mainly discussed based on experimental findings of many workers including those from our laboratory. In addition, morphological issues, like the structural integrity of the polymers that constitute the paint including crystallinity, have been shown to be responsible for the barrier performance. The issue of ionic resistivity is discussed from both the electrolytic pathway and ionic conduction approach. These combined mechanisms are important, as polymeric coatings are often exposed to atmospheric wetting and drying cycles which lead to a change in ionic resistivity behaviour due to "trapped salt" as well as its morphology. Finally, the performance of organic inhibitors in inhibiting corrosion and how it is related to the adsorption behaviour of the compounds to the substrate are discussed.
