After application and upon 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.
With an average thickness of at least 200 microns of CoppercoatTM marine antifoul being applied in a treatment, and a typical corrosion rate of 5 microns per year, it is easy to appreciate how this coating offers such long lasting and effective protection. During 2001, Yachting Monthly reported on a yacht that had been treated some 8 years previously. The verdict? “A great success”.
Furthermore, the inherent waterproofing qualities of the epoxy ensure that a treatment of CoppercoatTM marine antifoul will help prevent osmosis in GRP craft and offer extra protection against corrosion in steel vessels.
With the resin carrier insulating each copper sphere, the final coating is inert and non conductive. Consequently CoppercoatTM marine antifoul does not cause electrolysis problems or cathodic decay in steel or aluminium craft. Sacrificial anodes should be fitted in the usual manner.
CoppercoatTM is the obvious choice for owners searching for increased performance with reduced costs from
Unlike regular coatings, hardwearing CoppercoatTM remains effective for many seasons. A single treatment of CoppercoatTM is proven to remain effective for at least ten years. The first boats treated are still clean after 15 seasons!
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.
GRP osmosis protection
CoppercoatTM is based upon an inherently waterproof epoxy resin. As such, the application of CoppercoatTM helps to protect GRP vessels against osmotic attack.
No more expensive and unpleasant annual stripping and repainting of hulls. Simply hose down the hull at regular intervals (commonly once a year), to remove any build up of slime.
Being epoxy based CoppercoatTM is classified as non-eroding and causes less harm to the environment than conventional anti-foul paints. The complete treatment has been tested and approved by the Health and Safety Executive, in compliance with UK and EU law. Holding HSE Certificate Number 7532 our anti-fouling is fully approved for use by both professional tradesmen and the general public. Furthermore, CoppercoatTM fully complies with current (2001) International Maritime Organisation (IMO) Resolution MEPC.102(48).
These advantages have meant that many of the world’s leading boat builders have adopted CoppercoatTM.
How Much Will I Need?
To determine the quantity of CoppercoatTM required, calculate the hull area by simply multiplying the waterline length by the addition of the beam and the draft. Then, depending on the vessel, apply a factor:
-For full bodied craft such as motorboats or displacement and full keeled yachts, no factor is applied
-For medium bodied craft, such as large fin and skeg or bilge keeled yachts, multiply by a factor of 0.75.
If the calculation is in feet, multiply the figure by 0.093 to convert to square meters. Given that CoppercoatTM has an effective coverage rate of 4 square meters per litre; divide this figure by 4 to determine how many litres are required.
A 34ft motorboat, with a 30ft waterline length, a 12ft beam & a 2ft draft;
30 x (12+2) = 420sq.ft, x 0.093 = 39.06sq.m, / 4
= 9.76 litres required. As Coppercoat is supplied in 1 litre units, 10 litres should be used.
A 28ft fin keeled yacht, with a 26ft waterline length, a 11ft beam & a 5ft draft;
26 x (11+5) x 0.55 = 228sq.ft, x 0.093 = 21.27sq.m, / 4
= 5.31 litres required. As CoppercoatTM is supplied in 1 litre units, 6 litres should be used.
