    摘要: Disclosed are thermosetting, powder coating compositions comprised of a blend of semi-crystalline and amorphous polyesters and certain adducts of the 1,3-diazetidine-2,4-dione dimer of isophorone diisocyanate which are readily curable at temperatures and times commonly used to cure (cross-link) powder coatings. When using equivalent curing conditions, the disclosed coating compositions exhibit a higher degree of cross-linking than do combinations of amorphous polyesters alone and the adducts of the 1,3-diazetidine-2,4-dione dimer of isophorone diisocyanate.

    摘要: Provided are crosslinkable semicrystalline polyester plasticizers useful in thermosetting powder coating compositions. The plasticizers of the present invention are preferably comprised of residues of 1,6-hexanediol and 1,12-dodecanedioic acid, and optionally, residues of trifunctional acids or polyols such as trimethylol-propane, glycerol, trimellitic acid, and the like. The thermosetting powder coating compositions also provided by the present invention exhibit markedly superior properties when compared to compositions lacking said plasticizer. Such coatings exhibit better smoothness, less orange peel, better impact strength and flexibility. In the case of the less-reactive crosslinker such as self-blocked isophorone isocyanate (IPDI), the plasticizers greatly improve the reactivity of the composition and reduce the cure requirement.

    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.

    摘要: Disclosed is a process for isolating copolymers comprising repeating units from 2-vinylpyridine and styrene by drowning the reaction emulsion into an acetic acid solution or by adding an acetic acid/water solution to the reaction emulsion. The copolymer isolated by this technique filters and washes much more rapidly than the copolymer isolated using sodium chloride, and the wet cake has a high solids content.
