Study to Determine the Feasibility of Overcoating Coal Tar Enamel with Foul Release Coatings
Coal tar enamel provides superior corrosion protection and service life which is unmatched by modern coating systems. The cost of deploying a foul release coating could be lowered if the new system could be applied without removal of the coal tar enamel i.e. overcoating. Laboratory evaluations were conducted on four promising foul release coating systems. It was determined that overcoating is not recommended due to catostropic failures observed in testing.
