Abstract
This chapter discusses coating processes. Coating and paint technologies adapt to environmental requirements. The development of water-borne coatings and solvent-free coatings signify new health and safety trends in coating technology. Coatings can be classified in the following categories according to their corrosion resistance: barrier coatings, conversion coatings, anodic coatings, and cathodic coatings. Miscellaneous coatings include glass coatings, porcelain coatings, and high-temperature coatings. The coating system comprises the primer, intermediate coat, and top coat. The chapter discusses the advantages and disadvantages of various organic coatings. Binders are classified according to their chemical reactions. Pigment is a substance that is dispersed in a binder to give specific physical and chemical properties. Mechanistic understanding of failures of paints and coatings is important for engineers. The failures can be divided into four categories: formulation-related failures, adhesion-related failures, application-related failures, and design-related failures. Selection of an appropriate coating system is a prerequisite for the durability of a coating. In this respect, a list of factors is provided in the chapter.
