How does Coppercoat work?
Coppercoat is the combination of a specially developed two-pack epoxy resin and 99% pure copper. Each litre of Coppercoat contains 2kg of ultra fine copper powder, the maximum allowed by law. On immersion, sea water attacks the exposed pure copper powder, causing the formation of cuprous oxide. This highly effective anti-fouling agent deters growth until the surface degrades further to become cupric hydrochloride. This final copper form is highly unstable, and is washed away by the movement of the yacht, thereby removing any accumulating silt or slime. This automatically reveals a fresh copper-rich surface whereby the process recommences.
