ANALYSIS OF BUOY COATING SPECIMENS EXPOSED IN SEAWATER AT DAYTONA BEACH, FLORIDA

Eighteen premium antifouling marine coatings systems are being examined to determine extended service life potential. Premium systems were selected to contain combinations of (1) substrate, (2) pretreatments, (3) anticorrosive tiecoats, (4) antifouling topcoats, and (5) toxicants. Seawater immersion studies include both dynamic and static exposures. The performances of Type 121/63 and Type 121 vinyl-rosin controls and a proprietary elastomeric sheet with organotin toxicant have been rated 'outstanding'. Self-cure and postcure zinc primers with high-build vinyl anticorrosive and vinyl-rosin topcoats are rated 'excellent'. All of these five systems may meet the original 5-year performance goal and several may continue to perform well for many years to come. Performances of seven systems have been rated 'fair to good'. Performances of six systems have been rated 'failure'.
