Title: THERMOSETTING POWDER COATING COMPOSITION
Abstract:
A thermosetting powder coating composition comprising a fluoropolymer, a polyester polymer, and a hardener, wherein the fluoropolymer is a fluoropolymer (A) comprising fluoroolefin units and vinyl ester units and having crosslinkable reactive groups or the polyester polymer is a polyester polymer (I) comprising isophthalic acid units and/or 1,4-cyclohexanedicarboxylic acid units as essential structural units and having crosslinkable reactive groups. This composition can attain an improved balance between weatherability and coating film appearance, e.g., gloss and smoothness, although weatherability has been inconsistent with coating film appearance in thermosetting powder coating compositions.
