Abstract:

Performance is reported on ten generic types of protective coatings for steel exposed in two tropical and one subtropical marine atmospheric environments for periods up to 15 years. Zinc-rich coatings without topcoats and a modified phenolic system demonstrated long term protection of steel. Aluminum pigmentation in the topcoat was found to improve the performance of the protective system. Very good protection for a minimum of 4 years was demonstrated by vinyls with strontium chromate or red lead pigmentation in the primer, a coal-tar epoxy, a mica-filled asphalt emulsion, a modified phenolic mastic, an aluminum- pigmented coal-tar epoxy and zinc-rich coatings.
