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.First marketed under the brand name Copperbot by C-Defence International Ltd, this revolutionary coating has been soley manufactured and distributed by Aquarius Marine Coatings Ltd since January 1998, under the name COPPERCOAT.

On immersion sea water attacks the exposed pure copper powder, causing the formation of cuprous oxide. This highly effective antifouling 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.


Unlike regular coatings, hardwearing COPPERCOAT remains effective for many seasons. Research shows the expected lifespan of COPPERCOAT to be greater than 10 years.


The combination of high copper content and a unique blend of biocides ensures ultra low growth rates and a clean hull. Motorboat owners report increased speed at lower revs, meaning a lower rate of fuel consumption and less engine wear. Professional racers can burnish the surface if required.


OPPERCOAT is based upon an inherently waterproof epoxy resin. As such, the application of COPPERCOAT helps to protect GRP vessels against osmotic attack.
