How Coatings Protect Steel

This article describes how coatings protect steel. As an overview, the basic components of coatings and the function of each coat are discussed. Three mechanisms of protection are described in detail. The first is barrier protection, which is the prevention of moisture and oxygen from reaching steel surface. The second mechanism is inhibition, which is interference with the electrochemical process of corrosion. The third is sacrificial action, which is the consumption of zinc pigments in a primer rather than steel when corrosion occurs. Each of these mechanisms may involve the use of specialized pigments in the paint formulation.
