  • Coating compositions containing acid functional polyol polymers and coatings formed therefrom
    Patent number: 12071559
    Abstract: A coating composition includes: (a) an acid functional polyol polymer having an acid value of greater than 9 mg KOH/g and less than 60 mg KOH/g, and a hydroxyl value of from 100 to 300 mg KOH/g; (b) a non-aminoplast derived crosslinker reactive with the acid functional polyol polymer; and (c) a non-aqueous liquid medium. Further, an equivalent ratio of functional groups on the crosslinker reactive with hydroxyl functional groups to hydroxyl functional groups on the acid functional polyol polymer is within a range of from 0.5 to 1.5. The coating composition is substantially free of an external catalyst. The coating composition cures at a temperature of less than 80° C.

  • ELECTRODEPOSITABLE COATING COMPOSITIONS
    Publication number: 20220363917
    Abstract: The present invention is directed to an electrodepositable coating composition comprising an acrylic polymer comprising greater than 60% by weight of constitutional units comprising the residue of a hydroxyl-functional (meth)acrylate monomer and/or a hydroxyl-functional (meth)acrylamide monomer, based on the total weight of the acrylic polymer; and an ionic salt group-containing film-forming polymer different from the acrylic polymer. Also disclosed are coatings, coated substrates, and methods of coating a substrate.
