    摘要: The present invention relates to powder coating compositions and to components and ingredients for incorporation therein, suitable for fast curing schedule and with excellent resistance to outside aging. Non-isocyanurate polyepoxide cross-linking reagents can be used, provided the nature of the carboxylated polyester resin is formed of at least 30 mole % aromatic acid and the chain of the carboxyl terminated polyester also incorporates a moiety derived from 1,4 cyclohexanedicarboxylic acid. The powder coating composition can be cured for 90 seconds at a temperature of 250° C. or 55 seconds at 270° C. or 20 seconds in an induction oven at a temperature of 300° C. in the presence of a catalyst.
