Coppercoat is the combination of a specially developed solvent-free epoxy resin and high purity (99%) copper. Each litre of resin is impregnated with 2 kilos of ultra fine spherical copper powder, the maximum allowed by law, making Coppercoat the strongest copper based anti-fouling available. Indeed no other anti-fouling exposes as much active copper to unwanted marine life as Coppercoat.
