Self-polishing antifoulant with a copper-free biocide. When exposed to UV light, the nano-based technology copolymer releases the active non-metal biocide which dissipates in seconds without bio-accumulation into the environment. May be used on aluminum hulls without the use of a traditional barrier coat system. Ideal for all types of craft -  fiberglass to aluminum. Can be applied over other ablative antifoulant paints. Lloyd's Register certified.
