Anti-fouling paint that dries very fast?

[Venexiano]

Dear all,

Which anti-fouling paint do you suggest for the mooring of 3 bouys in a shallow harbour? I need my technicians to be able to use something that dries very fast, since they will pull up the mooring, clean it, dry it, paint it, and redeploy it from a boat. Paint will go on the line, chain, shakles, swivels, submerged part of bouy, and maybe bottom weight. Thank you very much

I don't know the answer - but I've never seen anti-fouling paint used that way. Especially not on the lines...

Based on the desire for extremely fast drying, you might look into VC-17, if it's still on the market.

VC17 dries in less than 5 minutes. Why does a buoy need bottom paint?

Most solvent based antifoulings dry in less than one hour. The advice is not to put them in the water for 24 hours, but it is common practice to paint the spots under the pads and launch in 30 minutes. Seems to work OK. Not water based paints!

West Marine PCA Gold on sail is a great value in a two year paint. Pettit make sit. If you are in Italy, try Pettit Odyssey.

But yes, most would not bother.

VC17 dried extremely fast (minutes on a warm breezy day), but not sure it works well in salt water. Used extensively on the Great Lakes in the US.

I would not bother painting the chain and shackles. The movement of the chain will wear away the paint pretty quickly. A lot of effort and expense for very little benefit. Painting the will not endear you to the users of the mooring as the paint will rub off on their boat, hands, and lines. Painting the bottom of the buoy might work, provided the solvents in the paint do not react with the plastic and foam of the buoy.

Wouldn't the copper react with the metal of the chain and other parts?

Hmmm, good question since the chain and other hardware are probably galvanized I suspect so.

Yep.... galvanization is zinc and zinc gives up its electrons more easily than copper. In fact it is zinc's ability to give up its electrons that makes it a good way to protect iron from rusting. As the iron's electron is lost to the environment, the zinc replaces the iron's electron (sacrificial). And the oxidized zinc oxide forms a nice hard coating that acts like a paint to slow further oxidation. Copper in the paint is in the +2 oxidation state so it is hungry for electrons... My educated guesss is that your zinc will oxidize more rapidly if you paint it with copper bottom paint...
