StaClean, a fluorourethane blade coating, was first used on wind turbine blades in New Hampshire, USA, in 1989 as an ice release coating. The coating is low friction (below Teflon), flexible and tough, and can be applied in the field or factory with conventional paint spray equipment. Blades at Tahacipi Pass were coated with StaClean, in the field, after ice formations caused problems. Inspections of the blades in 2004 showed excellent condition after 14 years’ operation, without recoating. Subsequent applications include release of insects in a desert area of Palm Springs, California, since 1992, and ice release in the Yukon, Canada, for arctic ice build-up prevention since 1994. All applications show improved power output and preservation of blades after 11 years.
