Intersleek 900 is a patented fluoropolymer foul release coating that does not contain any biocides. The finish has what is known as low surface energy. Fouling organisms generally have a difficult time forming an attachment to a low surface energy finish and when they are successful only do so very weakly. Fouling can be easily removed with simple hand cleaning methods using sponges, window squeegees, soft bristle brushes, and fleece mitts. The frequency and amount of cleaning required will depend on fouling conditions and how often the boat is used.
