  • New Anti-Fouling Paint Allows Growth to be Wiped Off With a Sponge

    Not sure how applicable this will be for subs, given the characteristics of traditional anechoic tiling, but it's pretty cool, nonetheless!

    It's made from a polymer composite based on polythiourethane (PTU) and specially-formed ceramic particles, which has an exceptionally smooth surface. Marine organisms can't form a permanent foothold on it, and those that temporarily do latch on are easily dislodged without damaging the paint itself.

    In a field test of the technology, the paint was applied to the hull of a ship that regularly travels between Belgium and Gabon in central Africa. Even after two years, there was still a marked reduction in biofouling. The organisms that were present were quickly cleaned off using a plain sponge.

    Phi-Stone is now working on a spraying technique for applying the paint over large areas.
