If you use the brand name Copper coat it is expensive but all that stuff about UV has been sorted out.
People have bought the ultra fine copper powder and mixed with their normal boat building epoxy and this has had problems. I have seen layers of this fall off.

Not much UV will get past the outer layer of copper powder. Metals are notoriously opaque. There may be other problems. Cheers,

I thought you can't do epoxy and copper powder, because epoxy cannot handle sunlight UV.
You have to add it to the paint, I thought.

| Epoxy with copper powder might actually be better than the poor antifouling-paint which falls off and is repainted with bad preparations and falls off even faster.
