Abstract
A powder coating composition can include: a polyester polymer comprising carboxylic acid functional groups; a crosslinker reactive with the carboxylic acid functional groups of the polyester polymer; and a thermoplastic fluoropolymer unreactive with the polyester polymer and crosslinker. The powder coating composition is substantially free of an isocyanate functional crosslinker.
