  • COATED SUBSTRATES AND METHODS OF PREPARING THE SAME
    Publication number: 20230167311
    Abstract: The present invention relates to a substrate having (a) a first material applied to at least a portion of the substrate, and (b) a coating layer deposited from a powder coating composition including a film-forming resin, and optionally a thermally conductive, electrically insulative filler material and/or a crosslinker that is reactive with the film-forming resin, in direct contact with at least a portion of the substrate to which the first material has been applied. The first material is (i) a catalyst that catalyzes cure of the powder coating composition, (ii) a component reactive with the film-forming resin and/or the crosslinker of the powder coating composition, and/or (iii) a rheology modifier.

  • Powder coating composition comprising an organometallic catalyst
    Patent number: 11345822
    Abstract: The present invention is directed to a powder coating composition including a hydroxy-functional polymer, a carbodiimide crosslinker, and an organometallic catalyst. The present invention is also directed to a substrate at least partially coated with the powder coating composition. The present invention is also directed to a method of applying a coating composition to a substrate including: applying the powder coating composition to a substrate and heating the powder coating composition to form a coating over the substrate.

  • Coating Compositions Containing Lignin and Coatings Formed Therefrom
    Publication number: 20210261789
    Abstract: A powder coating composition includes: a film-forming resin; a lignin polymer that is substantially free of sulfonate or sulfonic acid groups; and a crosslinker reactive with functional groups of the film-forming resin and the lignin polymer. The lignin polymer includes at least 5 weight % of the powder coating composition, based on the total solids weight of the powder coating composition. Further, when cured to form a coating, the film-forming resin and lignin polymer react and chemically bond with the crosslinker to form a binder of the coating.
