Accelerated corrosion test methods have been used for a long time to predict performance of coating systems in real applications. These methods have also been used for qualifying individual systems, and for benchmarking different systems in particular applications. Different accelerated methods have been developed over the years depending on which branch of the industry, or company in which they are used. Results from accelerated corrosion testing of paint systems, including pretreatments are described and compared to field testing for 18, 30 and 43 months in a marine atmosphere. Most of the paint systems and pretreatments tested are classified as relatively new, and environmentally friendly.
