Antifouling agents are essential for preventing the growth of marine organisms on a ship's submerged hull, which if not controlled proves to be costly to ship operators and as well as harmful to the environment. SEA-NINE® 211N antifouling agent represents a significant ecological advance for marine paints because of its environmentally acceptable properties: it degrades rapidly in sea water and sediment, does not bioaccumulate in marine species, and is not a chronic or reproductive toxin.
