Abstract

Organic Coatings are used for protection of metallic structures from corrosion. However they fail to isolate the substrate from corrosive materials present in the surroundings because the amount of water absorbed in coatings facilitates the movement of corrosive ions and gases through them, which in turn corrode the metal. The present studies illustrate the relative degree of permeation of chloride ions and water vapour through a variety of alkyd coating formulations.
