Anti-fouling paint
Anti-fouling paint - a category of commercially available underwater hull paints (also known as bottom paints) - is a specialized category of coatings applied as the outer (outboard) layer to the hull of a ship or boat, to slow the growth and/or facilitate detachment of subaquatic organisms that attach to the hull and can affect a vessel's performance and durability (see alsobiofouling). Anti-fouling paints are often applied as one component of multi-layer coating systems [1] which may have other functions in addition to theirantifouling properties, such as acting as a barrier against corrosion on metal hulls that will degrade and weaken the metal,[2] or improving the flow of water past the hull of a fishing vessel[3] or high-performance racing yacht. https://en.m.wikipedia.org/wiki/Anti-fouling_paint
