More Information
Summary:A curable film-forming composition is provided, comprising: (a) an acrylic polyol prepared from a monomer mixture comprising a hydroxyl functional monomer, wherein the hydroxyl functional monomer comprises a hydroxyalkyl group with an alkyl chain of at least four carbon atoms; (b) a rheology modifier comprising: (1 ) a non-aqueous dispersion of an internally crosslinked organic polymer; and (2) a reaction product of an amine and an isocyanate; and (c) a curing agent comprising functional groups that are reactive with hydroxyl functional groups. Also provided are a multi-component composite coating that includes the curable film-forming composition described above and methods for forming a composite coating on a substrate.
