    摘要: This invention provides weatherable thermosetting powder coating compositions based on 1,2-cyclohexanedicarboxylic acid and 2,2,4,4-tetramethyl-1,3-cyclobutanediol. Coatings from this invention exhibit far superior QUV (313 bulb) resistance than compositions based on resins prepared from 1,3-and 1,4-cyclohexanedicarboxylic acid and are 20 times better than standard aromatic resin using the same cross-linking chemistry.
