Hempel antifoul

[Lightwave395]

Does anyone know if there is any difference between HEMPEL'S CLASSIC 71220 and HEMPEL'S CLASSIC 76110 antifoulings other than price...?

The latter appears to be a commercial flavour - does that make it any more effective ?

If you look at the Safety Data sheets, they appear to be almost identical in composition. If anything, the 71220 has a higher specific gravity, which is usually a good indicator of copper content.

Thanks, I guess that might account for why the quoted thickness is higher on the 'commercial' version - thought for a minute I'f found a Seaquest replacement...!
