Typical service lifetimes for protective coating systems range from 10-50 years, depending on how extreme the service environment is, as well as on all the details of substrate preparation, coating composition, and coating application.4 While the primary consideration for specifiers of protective coating systems is the service life related to corrosion protection, there is often also a requirement of durability of decorative properties, e.g. color and gloss. This is true not only for monumental steel structures, but also for instance for industrial and offshore structures where “safety colors” are used. This segment therefore has many similarities to the “architectural coatings” segment (coatings for monumental buildings), where the substrates may be different, but where a multi-layer system approach is still used, and owners expect the durability of both the protective and decorative functions.
