About CopperCoat

Coppercoat is a non-ablative “hard” bottom paint that does not slough off in the water via friction. Coppercoat uses a specially developed zero VOC, water miscible epoxy resin and 99% pure copper powder (not cuprous oxide) to provide it’s antifouling ability.


  • 7-10 years between applications
  • 4.4 lbs of 99% pure ultra fine atomized copper powder per liter of epoxy
  • California EPA Reg. No. 85396-1-AA Compliant

Thoughts on Coppercoat the 10+ Year Antifouling Bottom Paint

When we started researching bottom paint we were looking for something that would be long lasting, minimize maintenance and be as environmentally friendly as possible. Coppercoat checked all those boxes and so far we are extremely happy with our choice!

Painting the hull of a boat is a tough job. But removing old paint is a HORRIBLE job.  Our first goal was to limit the number of times we’d do this over the years. We’ve heard of boats that had Coppercoat lasting 10+ years without re-applying – this was a big plus.

Rather than having poisonous chemicals leaching into the water in order to kill any life growing on or near our hull. Coppercoat works as a “deterrent”, meaning barnacles and other growth don’t attach to the hull.

Coppercoat is one of the hardest copper based anti-fouling coatings available, each liter of epoxy resin is combined with 4.4 lbs of ultra fine atomized copper powder, making it the strongest copper based anti-fouling available. But the difference is in the way Coppercoat exposes it’s copper to the water by retaining it in the epoxy, meaning the rate at which the copper is released into the environment is MUCH slower and lower than other ablative and non-ablative bottom paints containing copper or cuprous oxide.
