Probably just try a little test; as far as I can read from the TCM-guru threads, its really only effective against barnacles, rather than slime. Might mull about that.
OK, they sell three coppers, but not as coarse as 250micron. Its about £20-30 kg, plus £15 delivery, as its hazzardous....
Makes trilux look quite cheap, then !

Bought mine from here http://www.trylon.co.uk/products/filledcasting.htm. They were the cheapest.
Yes it has worked mixing it with Trilux, after 2 years no barnacles but we do have slime. Don't think there's anything that will stop that

wow lads
thats a very interesting idea! what approx quantity of powder should be mixed with say a gallon of antifouling, are there any special tecniques used?
because the barnacles sure love me

1kg. per litre of antifoul.

You're basically making Coppercoat, so the question is whether you can do it cheaper than they sell it.

Having done this two years ago, I'd say don't bother. It didn't make the (admittedly expensive and quite effective) Interspeed Ultra perform any differently.
Having said that, Cu dunked in a cheap a/f may make a difference.
Bear in mind that it's a bit pointless unless you've converted the copper to copper oxide - it's the copper oxide that's the effective agent. Liberal use of Jif lemons before getting the hull wet helps here.

1 x .500g Copper powder - 325 mesh = £7.75
------------------------------------------------------
Sub-Total: £7.75
UK Mainland Shipping ( kgs) (3 Days): £5.75
VAT (15%): £2.02
Total: £15.52
A tip: Use a proper drill driven stirrer and stir very well and only pour enough paint into your tray to do five minutes rolling. Before refilling the tray, stir thoroughly again. If you don't do this the copper sinks to the bottom and when you toss the almost empty tin into the bin, most of your expensive copper goes with it, or if you do use it all up, the last bit of antifoulling will be bullet proof.
Incidentally, a man who makes anti foul for a living told me that even if using factory stuff out of a tin, you should stir mechanically and keep stirring or all the good stuff sinks.

not so, as the a/foul doesnt need another good knows how many hours to get the a/foul primer off !!
But it was more out of curiosity; Trilux seems pretty good on its own for the last few seasons,so I ll just use that I think. Prop-shield seems to be acting more like a dinner plate than an antifoul....

Yes you can. About 1/2 the price and that included getting the local epoxy manufacturers to make up a batch of water based epoxy for me specially.
