The corrosion protection of rusted steel structures such as offshore platforms, bridges, pipelines, port installations and railcars is a major challenge to coating technologists. This article reviews the mechanism of corrosion and conventional approaches to formulating coatings for rusted steel, and then describes research on two new approaches to formulating coatings for rusted steel. The two coating formulations discussed are as follows: a water-borne, rust-tolerant coating (paint A); and a surface-tolerant, high-build, high performance, high volume solids coating (paint B). The details of the study are described, and the results are presented. It was found that paint A can assist in providing long-term protection. The corrosion protection of paint B was satisfactory. Paint A is recommended as a primer for coating systems applied in highly corrosive chemical environments as well as marine environments. Paint B is applicable at a high dry film thickness in a single coat.
