Unusual A/F question

[Wiggo]

A mate of mine is now working for a company that does underwater positioning systems. One of their challenges is antifouling, as their transponders are affected by barnacles and mussels, but less so by weed and slime.

What A/F would the panel recommend, given that there will be next to no water flow (other than tidal)?

International Micron 77, as this is a true self-polishing antifouling rather than an ablataive one. The key difference being that a true self-polishing antifoul effectively reacts with the water so that it gradually disolves, leaving a fresh layer of biocide laden paint to ward off fouling. It also means you can paint on as many coats as you like and it will carry on working for as long as the paint lasts.
Soft ablative antifouling such as International Extra and particularly hard ones such as Trilux rely on the motion of the boat or the tide to wear away the thin layer of 'dead' paint matrix from which all the biocides have leached out. Even then this 'dead' honeycomb matrix tends not to wear away smoothly or completely making it hard for the fresh layer underneath to work its magic.

Cuprotect / Cuniguard is widely used in the oil industry so would be ideal for this application.

coppercoat? brilliant at its job sh!t to use, my effort to paint our sonarbells resulted in two dodgy looking maltesers :-(


On another note, does anyone have a small amount of Intersleek knocking about? My mate needs a small quantity to finish a job and will pay cash. South Coast, Portland area...

We'll get CopperCoat on them for him. Will likely last 20 years, so copper has to be the answer if these thing don't wear out every year.
