Developed in the 1980’s and available to the public since 1991, CopperCoat is possibly the most powerful and long lasting anti-fouling available to the modern yachtsman This hard wearing densely copper filled epoxy resin is successfully protecting tens of thousands of boats the world over, saving their owners the time and expense of annual re-antifouling. Many users have now enjoyed more than 10 years continual protection from a single treatment! How it works 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 With an average thickness of 250 microns of COPPERCOAT being applied in a treatment, and a typical corrosion rate of less than 10 microns per year, it is easy to appreciate how this coating offers such effective and long lasting protection. Furthermore, the inherent waterproofing qualities of the epoxy ensures that a treatment of COPPERCOAT will help to prevent osmosis in GRP craft and offer extra protection against corrosion in steel vessels. With the resin carrier insulating each copper sphere, the total coating is inert and non-conductive. Consequently, COPPERCOAT does not cause electrolysis problems or cathodic decay on steel or aluminium craft. Sacrificial anodes should be fitted in the usual manner. Strength & Performance Since the banning of tin derivatives, copper has become the most popular metallic element in modern anti-fouls. However, only COPPERCOAT uses copper of 99% purity. This not only guarantees the maximum production of the powerful anti-fouling agent cuprous oxide, but also allows the correct rate of degeneration and exposure. Tests show that in products using less pure copper, or weaker alloys such as copper nickel, anti-fouling performance is substantially reduced - the inevitable result of a slower release rate and lower production of active cuprous oxide. When cured, the average pure copper content of modern COPPERCOAT is over 83% by weight, making it the most potent and copper rich anti-foul available to the general public. It is this unique combination of copper purity, quantity and small particle size that allows COPPERCOAT to create and expose more active cuprous oxide to marine fouling than any comparable product.
