Copper is expected to be re-approved as a biocide in California, under certain conditions. As part of the re-evaluation process, state legislation known as A.B. 425 required the coatings industry to conduct an in-water hull cleaning study to quantify the amount of copper leaching into the water column both passively, and as a result of hull cleaning/scrubbing. The results of the study were used to devise maximum leach rates, and those antifouling coatings over the limit, which are currently in use, will have to removed from the market.
The Marine Coatings Committee plans, identifies, and deals with problems specific to marine and offshore coatings manufacturers, and establishes and maintains communications with all segments of the marine industry, including shipbuilders, ship operators, naval architects and government agencies. Over the last several years, the committee’s issues have taken on an increasingly international component in light of the growing influence of international regulatory regimes affecting marine coatings. It works closely with the International Paint and Printing Ink Council’s (IPPIC) Marine Coatings Sector, which now has consultative status as a non-governmental organization with the International Maritime Organization (IMO).
ACA’s Antifouling Coatings Work Group is a subcommittee that was formed out of the efforts of the Marine Coatings Committee in the antifouling coatings area. It focuses on U.S. antifouling coatings issues and works primarily through coatings and raw material supplier ACA member company representatives
