SERVICE LIFE PERFORMANCE OF MARINE COATINGS AND PAINT SYSTEMS

Field inspection techniques were developed to evaluate the service life performance of coatings applied as protection to metal surfaces exposed to sea water, fresh water and sanitary waste. Data was obtained for Coal-tar epoxy, polyamide epoxy, inorganic zinc and zinc-dust paint systems. The surface area found to have failed by visual examination was used to compute a coating index (C) that ranged from 100 to 0. Data from a maximum of seven years of service allowed computation of a lower confidence limit for coating performance as a function of service time. Coal-tar epoxy gave excellent protection for six years while the other coatings exhibited varying degrees of failure after four years.
