Abstract Epoxy adhesives were used to produce strong and durable bonds between steel and four types of vulcanized elastomer. Chlorination of the elastomer surface prior to bonding and the use of an epoxy primer on the grit blasted steel surface gave the best results in laboratory trials as well as after tropical marine immersion for three years. A layer of natural rubber approximately 6 mm thick was found to be sufficient, if correctly bonded, to prevent completely the corrosion of mild steel during three years' immersion in tropical seawater. This system also performed well under dynamic flow conditions which were equivalent to a vessel travelling at a speed of 20 knots for 450,000 km.
