Beschreibung
Zusammenfassung:	The present invention relates to a powder coating composition comprising at least one fluoropolymer resin, at least one polyester resin, and an isocyanate crosslinking agent; wherein the molar ratio of isocyanate groups of the isocyanate crosslinking agent to hydroxyl groups of the polyester resin in the composition is from 2.5 to 5.The present invention further relates to a method for producing said powder coating composition, to the use of said powder coating composition for architectural powder coating, and to a powder coating obtained by applying and curing said powder coating composition.
