Performance of Ten Generic Coatings During 15 Years of Exposure.

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.
