Abstract : Several catalytically cured coatings can be applied to wet steel surfaces, but cannot be applied to steel surfaces completely immersed in seawater. The concept of using magnetic particles as part of the pigmentation and applying the paint under water to magnetized steel was investigated. Promising results were obtained from a magnetically pigmented epoxy and coal-tar epoxy. However, methods for inducing a stronger magnetic charge on the steel substrate are necessary. It is recommended that additional coatings, types of magnetic particles and methods to produce stronger magnetic charge on the steel substrate be investigated.
