Antifoul Paint - Do you add any 'extras'

Tributyltin oxide (TBTO)

I even wondered about just adding a cup full of fine cooper filings from the machine shop to a 4 litre (gallon) can.

Just wondering what the experiences have been of those people who've tried any all of these. Particularly with soft ablative paint for yachts.

Instead of copper filings, get a few tubes of copper radiator stop leak. Many a boatie in St.Thomas add these into the mix.. Can't say how successful it is as I'm one of the so called "douchebags" that uses TBT Bottom Paint and also add the TBT booster available in all of the Chandleries in SXM.

In nanny cay I used sea hawk island 47 with extra tin and in the primer I added cupric sulfate 6$ worth from amazon. It's working great with creeters in green cay marina in St Croix.

Sorry chief, you are sadly misinformed.

Adding chilli powder works well. I added 100g of Hot Chilli Powder per 2.5 litres of antifouling paint. I did test areas with and without the chilli. The result, after six months in a high growth area, was convincing. The downside is that it makes the surface a bit rougher. Why dry, I lightly sanded the surface before the boat went back in the water.

Underwater drones coming out, good ones, add a small platform on top of the drone, use PVC to shape a enclosed container of gunpowder and ball bearings. Add magnets to adhere to a metal hull.
Boom...old freighter becomes a reef.

Douche bags fiberglass boats a possibility also.
Paint number of boats sunk somewhere obvious like WWII subs, ship's, planes do, and planes today.

What a dream

Yeah right.. I'd suggest you read section b regarding federal law and TBT being exempt for boats 65' or larger. Also even though the US pushed as hard for this as they did to allow Monsanto to poison Americans with GMO's, the rest of the world really didn't go along with it.. OR the GMO crap either..http://nsglc.olemiss.edu/Advisory/Antifouling.pdf

Referring to some mythical "section b" without providing a quote or a link proves nothing, except that you failed to back up your assertions with actual facts. But the fact remains, you stated unequivically that "every single commercial boat in the world" is using TbT paint. Again, this so far from the truth that it is laughable, and I challenge you to provide a single scrap of evidence that it is true.

It keeps the barnacles happy.

Wise ass. What about a jigger of Scotch per gallon.

Your informations is years out fo date. Here is what I found when doing some quick research on the subject. This is the gist of the International Maritime Organization's ban on TbT anti fouling paints:

International Convention on the Control of Harmful Anti-fouling Systems on Ships

Adoption: 5 October 2001; Entry into force: 17 September 2008

​The Convention prohibits the use of harmful organotins in anti-fouling paints used on ships and establishes a mechanism to prevent the potential future use of other harmful substances in anti-fouling systems.

Annex I states that all ships shall not apply or re-apply organotins compounds which act as biocides in anti-fouling systems. This applies to all ships (including fixed and floating platforms, floating storage units (FSUs), and Floating Production Storage and Offtake units (FPSOs).


This is the President of the United States, George W. Bush, asking the Senate in 2008n to ratify the ban, which they did:

TO THE SENATE OF THE UNITED STATES:

I transmit herewith, for the advice and consent of the Senate to its ratification, the International Convention on the Control of Harmful Anti-Fouling Systems on Ships, 2001 (the "Convention").

Organotin-based anti-fouling systems are specifically regulated through the Organotin Anti-Fouling Paint Control Act of 1988 (OAPCA), 33 U.S.C. 2401-2410. New legislation is required to fully implement the Convention and will take the form of a complete revision and replacement of OAPCA. All interested executive branch agencies support ratification.

I recommend that the Senate give early and favorable consideration to the Convention and give its advice and consent to its ratification, with the declaration set out in the analysis of Article 16 in the attached article-by-article analysis.

GEORGE W. BUSH

THE WHITE HOUSE,

January 22, 2008.


Here is the U.S. Coast Guard Commander in 2012, giving instruction on enforcing the ban on TbT anti fouling paints in U.S. territorial waters:

A bit off subject

Now dont write" fstttmms" off.

We come from a farm in an area growing Macadamia nuts which attracts " lots" of bush rats which have an appetite for insulation on electrical wiring. I had a car destroyed and written off by them , we stopped them with a concoction of getting some of those small red hot chillies boiling them down to just a small amount of remaining fluid and spraying it diluted 60% water 40% chilly liquid , and spraying it all over car /tractor /machinery wiring , that stopped them completely! Should be absolutely useless information in a Yacht?

Jeezus- the reason adding peppers to anti fouling paint doesn't do anything is because the fouling organisms don't eat the paint. And even if they did, there is zero evidence that peppers increases the efficacy of anti fouling paint, despite what the occasional kitchen sink chemist or old salt from 3 slips down might infer.

Are you discounting my evidence above?

Yes. You don't have any evidence. What you have is an anecdote with nothing to back it up.

interesting idea to use additives in the paint, but I would think you'd need more than vigorous stirring to do anything other than suspend the poisons in the paint. how do you know the additive is getting out of the paint and into the water?

nothing works for me except to use the boat at least every other day, no growth or slime at all with ablative paint if you can move often.

I have been told! Anti Biotics. Dosage enough to dose a horse per litre.
