摘要： 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.

摘要： Disclosed herein are epoxy-polysiloxane polymer coating compositions suitable for coating surfaces that provide excellent chemical, corrosion, or weather resistance. The epoxy-polysiloxane polymer coating compositions include polysiloxane and non-aromatic epoxide resins, and a cure system, wherein the combined composition reacts to form a cross-linked epoxy-polysiloxane polymer structure. The cure system can include at least a blend of metal or organic catalyst(s) and alkoxy functional aminosilane(s), and may further include a polyurethane, such as a silane terminated polyurethane. The metal catalyst may be coordinated with, or in close proximity to, the polyurethane, thus providing excellent hardening results at very low metal concentrations.
