  • Publication number: 20200325289
    Abstract: A curable film-forming composition is provided, comprising: (a) a polymeric binder comprising epoxy functional groups; (b) a curing agent comprising acid functional groups that are reactive with the epoxy functional groups of (a); (c) a non-aqueous dispersion comprising a dispersion polymerization reaction product of a reaction mixture comprising an ethylenically unsaturated monomer and a nonlinear, random, acrylic polymer stabilizer; and (d) fumed silica. The dispersion polymerization reaction product in the non-aqueous dispersion (c) is present in the curable film-forming composition in an amount of 0.5 to 10 percent by weight, and the fumed silica (d) is present in an amount of 0.5 to 5 percent by weight, based on the total weight of resin solids in the curable film-forming composition. Also provided are multi-layer coated articles that include the curable film-forming compositions described above.
