The invention relates to coating compositions which have a low VOC (less than 250 g/l), are fast drying, and have excellent erosion resistance. These coating compositions comprise a film forming resin comprise one or more polyamine(s) containing secondary amine groups and specific aliphatic and/or aromatic esters. The coating compositions are particularly suitable for use in coating wind blades. The present invention also relates to a method of protecting a substrate against rain erosion or solid particle erosion using the coating composition, a coated wind blade or a part thereof, and the use of specific ester(s) in a polyurea-based coating composition for improving the rain erosion resistance or solid-particle erosion resistance of a coating.
