AkzoNobel ship hull anti-foul coating
Develop an anti-foul coating that is environmentally benign.
Ships lose sailing performance and develop damage due to fouling which occurs when organisms such as barnacles attach themselves to a vessel’s hull. The usual approach is to coat the hull in a biocidal paint – typically a tin-based poison.
Intersleek provides a slippery, hydrophobic, low-friction surface on which fouling organisms have difficulty settling. Those that do can usually be easily removed by simple wiping/washing, or by the vessel moving through the water at speed. Intersleek is a unique, patented fluoropolymer foul release coating that allows all vessels above 10 knots – including scheduled ships, tankers, bulk vessels, general cargo ships and feeder containers – to benefit from foul release technology. The coating has a secondary benefit of reducing drag of the hull, improving efficiency through the water.
