  • Publication number: 20220332973
    Abstract: A coating composition includes: an aqueous medium; a first polymer comprising first core-shell particles dispersed in the aqueous medium, where the first core-shell particles include (i) keto and/or aldo functional groups, (ii) a polymeric shell including carboxylic acid functional groups and urethane and/or urea linkages, and (iii) a polymeric core at least partially encapsulated by the polymeric shell, where the polymeric shell and/or the polymeric core include the keto and/or aldo functional groups; a second polymer dispersed in the aqueous medium, the second polymer including carboxylic acid functional groups and hydroxyl functional groups; a first crosslinker including a polyhydrazide reactive with the first core-shell particles; and a second crosslinker reactive with the first core-shell particles and/or the second polymer, where the polymeric core of the first core-shell particles are covalently bonded to at least a portion of the corresponding polymeric shell.

  • Publication number: 20220220335
    Abstract: A coating composition for precision application includes: a coating composition including a film-forming resin dispersed in an aqueous medium; a crosslinker reactive with the film-forming resin; a rheology modifier; a colorant; and a swelling solvent that swells the film-forming resin. The solids content of the coating composition is less than 25 weight %, based on the total weight of the coating composition. A system and method for precision application of a coating composition over at least a portion of a substrate are also disclosed. A substrate coated with a multi-layer coating system is also disclosed.

  • Publication number: 20210040350
    Abstract: A coating composition includes: an aqueous medium; first core-shell particles dispersed in the aqueous medium, where the first core-shell particles include (i) keto and/or aldo functional groups, (ii) a polymeric shell including carboxylic acid functional groups and urethane linkages, and (iii) a polymeric core at least partially encapsulated by the polymeric shell, where the polymeric shell and/or the polymeric core may comprise the keto and/or aldo functional groups; second core-shell particles dispersed in the aqueous medium, where the second core-shell particles are different from the first core-shell particles and include (a) a polymeric shell including carboxylic acid functional groups and hydroxyl groups, and (b) a polymeric core including hydroxyl functional groups and which is at least partially encapsulated by the polymeric shell; a first crosslinker including a polyhydrazide reactive with the first core-shell particles; and a second crosslinker reactive with the first and second core-shell particle

  • Publication number: 20200332145
    Abstract: The present invention relates to an aqueous coating composition comprising: (a) a film-forming resin selected from polyesters made from monomers comprising a polyetherpolyol and a polycarboxylic acid, the polyester bearing functional groups and having a Tg of less than ?10° C. measured according to ASTM D3418-15 (midpoint temperature, at a heating rate of 20° C./min); (b) a rheology modifier selected from inorganic and resinous rheology modifiers and combinations thereof; (c) one or more color-imparting pigments or effect pigments or combinations thereof; and (d) one or more cross-linking agents that are reactive with the functional groups of the film-forming resin according to a), wherein the coating composition exhibits a low shear viscosity of 0.5 to 40 Pas at 0.1 s?1 at 25° C.
