FIRST, I am not connected with any supplier in an way. Just a user/shopper.
I wish I could direct you to the CopperPoxy page, but they will not sell to us mortals any more.
I ordered my copper and epoxy from Progressive Epoxy Polymers, Inc., at: http://www.epoxyproducts.com/copper4u.html
The page gives a LOT of info on using it. BUT it states that it's up to the user! I also have to warn you that the site is hard to follow. It's getting better, but still a bit of a challenge to work your way to the spot to order the product.
I plan to mix it as suggested on the page. That is, “Add between 3 - 6 pounds of copper per gallon of our 810 epoxy.” This copper is about 41 micron flakes, a bit bigger than the copper used in the original CopperPoxy, (10 micron spheres) but I think it should work just as good.
After our upcoming haul out, next month, I will try to post some words and photos on our web pages in the “Position reports” area.
