Abstract
Requirements for a practical system to evaluate ship bottom coatings are listed. Panel trials are shown to be better than service trials for coating evaluations. Application of the d-c technique of coating evaluation is illustrated by comparison of three coating systems in static immersion and by a study of the influence of number of coats on performance. Investigation of drydock variables shows the reduction in coating performance resulting from rusting and the detrimental effect of 5 percent H3PO4 as an inhibitor after sandblasting. 2.1.2Keywords
