Abstract: A melt extrudable low temperature curable powder coating composition for application onto heat sensitive substrates. The final cured coating produces a low gloss finish on the target substrate. The composition consists of an unsaturated polyester resin combined with a glycidyl functional acrylic resin, a crystalline or semi-crystalline polycarboxylic acid or anhydride and a free radical initiator. Optionally, if a harder, more wear-resistant surface is desired, the cure may be catalyzed by either a photoinitiator or a redox compound.
