Abstract:
The present invention relates to a powder coating composition comprising at least one fluoro-modified polyurethane (meth)acrylate prepared from an isocyanate component, at least one hydroxy-C2-C4-alkyl (meth)acrylate and an alcohol component comprising at least one perfluoroalkyl alcohol are reacted stoichiometrically with one another, providing the powder coating composition a fluorine content (calculated as elementary fluorine with molecular mass 19) in a range of 0.1 to 3 wt%, the wt% based on the total weight of the powder coating composition. The powder coating composition according to the invention based on the fluoromodified polyurethane (meth)acrylate provides a highly improved flow, chemical resistance and particularly an improved and sustainable self-cleaning effect of the coatings.
