Abstract: Provided are thermosetting powder coating compositions comprised of an aliphatic carboxyl resin, a beta -hydroxylalkyl amide crosslinker, and a catalyst comprised of a C1-C18 carboxylate salt of a metal selected from the group consisting of zinc, aluminum, and titanium, or an oxide of aluminum or zinc. Preferably, the aliphatic resin is comprised of residues of 1,4-cyclohexanedicarboxylic acid (CHDA) and 2,2,4,4-tetramethyl-1,3-cyclobutanediol or comprised of 1,4-CHDA and hydrogenated bisphenol A. We have found that certain compounds, particularly certain zinc salts, catalyze the crosslinking reaction and significantly reduce gel time.
