Summary: | A powder coating composition can include: a polyester polymer having carboxylic acid functional groups; a first crosslinker reactive with the carboxylic acid functional groups of the polyester polymer; and a fluoropolymer unreactive with the polyester polymer and first crosslinker. A weight ratio of the polyester polymer to the fluoropolymer is from 80:20 to 60:40. When cured, the powder coating composition forms a single coating layer including the polyester polymer and the fluoropolymer. |
