Years ago, mariners covered the hulls of vessels with copper sheeting to provide anti-fouling properties. Today, Corrocoat Biofoul, a heavy-duty anti-fouling coating, works in a similar way, presenting a protective, copper-rich surface to fouling agents.
Applied by Leeds-based corrosion protection and engineering services specialist Corroserve, Biofoul is a non-toxic coating containing inorganic copper flakes. It is formulated as a durable, long-life coating that can withstand flow velocities in excess of 25 m/s. It works by the dissolution of metallic copper ions into the surrounding environment. This acts to inhibit fouling organisms attaching to the treated surface.
