Abstract
A curable film-forming composition is provided, comprising: (a) a polymeric binder comprising reactive functional groups; (b) a curing agent comprising functional groups that are reactive with the reactive functional groups of (a); and (c) a polysiloxane resin comprising aromatic functional groups and terminal active hydrogen groups. In certain examples of the present invention, the polymeric binder (a) comprises an acrylic polyol prepared from a monomer mixture comprising a hydroxyl functional monomer, and the curable film-forming composition further comprises a rheology modifier comprising: (1) a non-aqueous dispersion of an internally crosslinked organic polymer; (2) a silica dispersion; and/or (3) a reaction product of an amine and an isocyanate. Also provided are coated substrates that include the curable film-forming compositions described above and methods for forming a composite coating on a substrate.
