COATINGS FOR TROPICAL EXPOSURES

Before coatings are applied to structures in tropical and subtropical environments, the locally prevailing environmental conditions must be addressed. Different tropical and subtropical locations have unique conditions that will affect the materials selection as well as surface preparation and application methods. This article describes these conditions and how to minimize their detrimental effects. Tropical environments are among the most destructive for metals and their coatings. Each important tropical condition affecting coating application and performance--high temperatures, intense solar radiation, salt spray, heavy tropical rainfall, high humidity, and remoteness from suppliers and support services--is discussed individually, although there are usually many interrelationships between them. Mitigation approaches include controlling the environment using dehumidification equipment or other methods, using special spray painting equipment, and selecting coatings suited to the application and service conditions. Mildew defacement of coatings is such a widespread problem at tropical locations that it is addressed in a separate section. Such damage can be controlled through structural design and coating formulations.
