Embodiment Construction
[0023] The present invention relates to new coating compositions for wind turbine blades, wherein the base composition comprises a polyether aspartate having the following formula (I)
[0024]
[0025] where each R represents a linear or branched C 1 -C 10 Alkyl residues, such as straight or branched C 1 -C 6 Alkyl residues such as, for example, methyl, ethyl, propyl or butyl residues; and wherein X is a polyether. The coating composition also includes a curing agent.
[0026] Polyether aspartates differ from more conventional aliphatic polyaspartates in that X in aliphatic polyaspartates is typically an aliphatic straight or branched chain alkyl and / or ring Alkyl residues, not polyethers.
[0027] In one embodiment, the present invention is directed to coating compositions comprising a blend of polyether aspartates, wherein X is a polyether having repeating units of the following structure:
[0028]
[0029] where m is in the range of 2 to 35.
[0030] The blend ...

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.
Description
technical field [0001] The present invention relates to coating compositions for wind turbine blades. These compositions are especially useful as topcoat compositions or as compositions for leading edge protection (LEP). The present invention also relates to wind blades, such as the leading edge of a wind blade coated with the coating composition of the invention; and methods for applying the coating composition; and repairing and repairing by applying the coating composition of the invention and / or methods of replacing existing coatings on wind blades. The invention also relates to kits of parts comprising the base composition and curing agent used in these coating compositions. Background technique [0002] In recent years, wind energy has become an important source of electricity production and is very important for reducing CO 2 Emissions contribute significantly. Wind power is the use of airflow through wind turbines to provide mechanical power to turn an electrical...
