What type of antifouling or foul-release coating will provide the greatest protection in warm tropical waters, and for how long?


Selected Answers

From Alfredo Claussen of Instituto Mexicano del Petroleo on April 21, 2017:
I had the same need for an antifouling coating, not for a ship, but to paint a high visibility coating over an underwater template, so that divers or ROVs could find it easier to see after some time. But with the ever-present "ecological" arguments against any "toxic" or "ecologically unfriendly" coatings having  displaced copper paints, manufacturers have turned towards very slippery coatings that depend on movement for the ship to stay clean. Therefore, for a fixed object I'm still waiting a response from manufacturers. And I asked for a proposed system about three years ago! Any suggestion or discussion will be very highly appreciated.

No replies from paint manufacturers!?

From Colin Anderson of American Chemet on March 22, 2017:
A copper-based SPC (self-polishing copolymer) boosted with copper pyrithione, or a foul-release coating boosted with copper pyrithione, will give the best protection. These have the ability to last for up to 60 months, if groomed (lightly wiped) regularly.

From Per Gabrielsson of Free Lance Consultations and Inspections on March 22, 2017:
It would be very interesting to learn how and why paint manufacturers classify their different products. Always when bringing new products on the market, they claim that this is now the top! For static objects, the best solution would be a hard, brushable coating. Some hard coatings come with warranties up to 10-15 years.
