Juton Sea-Force Antifouling Paint

Has anybody used this stuff, and if so, what do you think about its use in the tropics (Caribbean/South Pacific)?

I put Juton on my boat while in Trinidad. I dont know if it was Sea Force or not. 1 year later returned the boat to Florida. She was docked in a backwater canal for 1.5 years after that while for sale. Growth abounded on everything around my boat. pilings, cement bulkhead etc. I hired a diver to scrub the bottom fearing it would look like a rock quarry. He came up out of the water and told me "there is nothing to do it's perfectly clean" 2.5 years is fairly good I would say..... You must be importing it...? Never mind , dont want to know!

thanks

Thanks for your response. We're currently in Trinidad where this stuff is available. Sure sounds like it's good stuff -- Chris

sea force 60 is good for the med. and for the atlantic you have to use sea force 90 that will give you good protection for about 5 years.

We currently have Jotun Sea Queen antifoul on the hull. It was applied in July 2007 and is going strong. Almost zero fouling, just a little slime along the waterline. Currently in the Caribbean.
This is the best result we have had. Used Sea hawk 44 with added tin last and it was useless within 14 months, prior to that a Hempel product that had to be replaced within 8 months....

yea, Jotun is what antifouling is supposed to be. US paint is worthless, might as well just hang in the slings once a year and pressure wash....

some more info regarding Sea Force (this is paint for big ships) sea force 60 will last for 60 month and sea force 90 will last for 90 month !!!! There is also sea force 30 and this one will last for 36 month.you have to mix this paint very much since the copper is sticking in the bottom of the bucket.

IIRC Trinidad was one of the last places on earth where bottom paint based on tin (TBT) was still legally sold. If this is a TBT-based paint, it is illegal to bring into the US, even on your hull. Same thing for most of the world.

Effective, yes, but your boat might be impounded, among other expenses.

Juton Seaforce 60 specs...
"
Antifouling SeaForce 60 is a high solids self-polishing antifouling based on Polymeric Plasticizer
Technology (patented). The tailor made balance of polishing behavior and release of high
performance biocides ensures good antifouling performance throughout the dry-docking interval. IMO
Anti-fouling System Convention compliant (AFS/CONF/26). "

Doesn't appear to use Tin. Also its convention compliant.

Re: Juton Sea-Force Antifouling Paint

Old thread but anyways, we just bought a can of Jotun Seaforce 60. Before, we had International Micron WA on our boat with very poor results.

I was planning to put on a layer of Primocon to get good holding and then put 3-4 layers of Seaforce 60 on that. Now someone told me that Seaforce 60 is a silicone-based antifouling and it won't work with Primocon as a base layer.

Is someone else using this antifouling? And if so, how did you apply it?

Re: Juton Sea-Force Antifouling Paint

Here is the data sheet for Seaforce 60 https://www.jotun.com/Datasheets/Dow...0__Euk__GB.pdf
Doesn’t look to be silicone based to me. But I think using there recommended primer would be best.

Re: Juton Sea-Force Antifouling Paint

I have used Jotun seaforce the last 3 haul-outs in Thailand and Malaysia. On bare metal (stainless strut) we used Jota-etch primer, followed by International Primacon. I have a steel hull, so on that we use a heavy build up of Jotamastic epoxy primer coats, then Primacon, then the antifoul, all done within time and temp specs to ensure chemical hook.

One more note, I previously used Jotun Vinyguard. For some reason the antifoul failed on that stuff. Peeled off after 6 months.

Re: Juton Sea-Force Antifouling Paint

Hi svloki, thanks for the information. So it looks like i will simply use Primocon as well, as it will probably be difficult to source the recommended primer (Jotun Seaforce) in Grenada.
