SR-21 Fresh Water Antifouling Speed Coating is an ultra-thin, super slick, low friction film for boat bottoms. It is the ideal racing finish for fresh water or cold saltwater boats. SR-21 combines copper powder and Irgarol, a slime reducing biocide, to produce an effective, thin antifouling film that prevents the attachment of fouling organisms such as barnacles, bryozoa, toredos, zebra mussels and algae. SR-21 contains two slicking agents PTFE (polytetrafluoroethylen) and Molybdenum Disulfide which reduce surface friction allowing the hull to slide through the water. SR-21 is recommended for use on fiberglass, wood and properly primed steel boats. It is easy to apply and dries in 15 minutes. Color changes upon immersion.
