Abstract: The present invention relates to coating compositions for wind turbine blades. The compositions are particularly useful as topcoats for wind blades and for Leading Edge Protection (LEP). The invention also relates to a wind blade coated with a coating composition of the invention and to a method for application of the coating composition and to a method for repairing and/or replacing the existing coating layer on a wind blade by application of a coating composition of the invention. The invention also relates to a kit of parts comprising the base composition and the curing agent used in the coating composition. The coating composition used for coating a wind blade comprises a base composition comprising a polyetheraspartic ester having the formula (I) below, wherein each R represents a linear or branched C1-C10 alkyl residue, such as a linear or branched C1-C6 alkyl residue, such as for example a methyl, ethyl, propyl or butyl residue; and wherein X is a polyether. The coating composition further comprises a curing agent.

Abstract: Described herein is a wind blade comprising an outer surface, and at least one coating layer applied to a part of the outer surface, the at least one coating layer including a first coating layer comprising: a) a primary composition comprising one or more aqueous dispersion of an aliphatic polyurethane; wherein said aqueous dispersion has a particle size characterized by a D50 (median) value below 1000 nm; and optionally b) a secondary composition comprising one or more polyisocyanates; wherein when the coating composition comprises b) then said aqueous dispersion in a) is present in an amount of at least 5 times the amount of said polyisocyanate in b) based on weight; when b) is absent then the coating composition is a one-component composition.
