RELATION BETWEEN CHANGES IN ELECTRICAL PROPERTIES AND PERFORMANCE OF COATINGS. EXPERIMENTS WITH THIRTEEN IMMERSED COATING SYSTEMS.

Abstract

In an attempt to find a relatively rapid method of predicting the performance of coatings, changes in electrical properties were compared with the results of long-term field performance of the coatings. Thirteen coating systems on steel panels were immersed in seawater in the laboratory for 400 days, and the AC and CC electrical properties of the coatings were determined. Earlier experiments had indicated a relationship between changes in electrical properties and performance. New results with coatings of comparatively good performance indicates some correlation between changes in electrical properties and coating performance. However, the correlation is not sufficiently high to allow reliable prediction of the comparative performance of good coatings.
