The results of the antifouling effect test over 5 years were announced, and it was proved that the copper coat is superior to other products.

The world renowned independent testing and research facility Plymouth Marine Laboratory Applications Ltd (with over 500 global partners) has recently published the results of their 5 year anti-foul trial. This process tested products from many of the major anti-foul manufacturers, and involved test panels attached to a frame anchored to the sea-bed of an area of high tidal flow. At the end of the trial the panels were checked for their performance, both in terms of anti-fouling (i.e. how clean they had remained) and their physical condition (i.e. how much of the original thickness had been lost).

To quote from the report: “After 60 months of testing, Coppercoat was the best performing coating.”

It goes on to say: “Coppercoat showed little significant change in thickness over time.” Indeed, we would have been delighted to see the trial continue for a further 5 years, or more! But with many of the other coatings having already completely failed, it was decided there was little point in such an extension.
