Jotun Antifoul

[stuartwineberg]

Hi Stuart

I have been talking at some length with both SML Marine Paints and Bayside Marine (both Jotun agents) about what is actually in Mare Nostrum and basically it is not as strong as the old Seaqueen and you gets what you pay for being

However after much discussion the one I will go for although much dearer but still cheaper than many is Jotun None Stop which you can buy and the specification is much higher and I have decided thats the one I will try when I lift out in the coming months, however I will put it ontop of a Primer as I did before when I apply any antifoul.

Thanks for that, but what a price difference

Yep. Used it a few years back before I changed to sea queen. Not bad and better I found than the usual chandlery brands of similar prices or more. I am trying mare nostrum this year. If it's no good then eu45 is what I will go back to if I still can't get any jotun pro stuff.

No, it is definitely nothing to do with application. You have to show it is for use on a commercial vessel. The evidence required is a coding certificate or equivalent.

So I must understand I have been lucky when I succeeded in convincing the local Jotun to sell me some Seaforce 60 (to be used next spring)...
Great antifoul: last application is spring 2011 !!!
Death to Jotun bean counters!

Anyone tried this one...? http://www.antifouldirect.com/index.html

Looks like a very good price if it works.

Looks like same stuff as EU-45 (45% copper).

Checking the data sheets, EU45 has a density of 1.9, Hempel/Bakes Basic has a density of 1.4, their Tiger is 1.7. This seems to indicate to me a very high copper content. Whether is 'active' copper is another question. I am prepared to give it a go this spring.

I had to buy Mare Nostrum last year - one half of the hull was Seaqueen and the other half Mare Nostrum and I was hoping to be at the yard when my boat was lifted out but unfortunately they took it out a day earlier! so did not get to see the difference.
This year it will be EU45.

Talked at length with the ever helpfull SMS paints today:

Mare Nostrum
contains:
Dicopper Oxide 7 – 25%
Zinc Oxide 2.5 – 25%
Specific Gravity 1.5 – 1.7

NonStop
contains:
Dicopper Oxide 25% - 35%
Zinc Oxide 2.5 – 25%
Copper <25%
Specific Gravity 1.7 – 1.9

Note that NonStop contains an additional ingredient – “copper”, which is not present in the Mare Nostrum Safety Sheet. Unfortunately I’m afraid I don’t know how this differs from Dicopper Oxide (maybe it’s copper powder??)

Beware of reading too much into the SG, as the paint binder can have an SG significantly greater than 1 and could therefore contribute to a high overall figure. I’m always a bit baffled by the 45% figures quoted, as copper has an SG of 7, so if almost half the contents were copper, then the SG ought to be significantly greater than 1.9. Maybe I’m missing something…

Anyhow I will try the Nonestop and report back in two years when I lift out again!

It was rubbish, i gave it the benefit of the doubt and tried it again last year - still rubbish.
