Hull Coating Leachate

Note: The documents on this webpage were generated a number of years ago. Some of the documents and data within may have been succeeded by more recent efforts.

Hull coating leachate consists of constituents that leach, dissolve, ablate, or erode from the paint on the vessel’s hull into the surrounding water. The anticipated standard will require Armed Forces vessels to use antifouling paints that meet a maximum allowable copper release rate.
