High quality self-polishing antifouling, based on copper and on organic substances with synergetic action. Especially suitable for boat hulls that are sailing at moderate speed (< 25 knots). The patented binder technology avoids fouling heap over time. The controlled release of active components achieves a perfect long-lasting antifouling function that is renewed by the friction of water on the hull. The white version of this product is usable on aluminium and its alloys, while the coloured versions are not compatible with these substrates.
