Methods of preparing coated substrates and non-aqueous, curable film-forming compositions used therefor

Abstract

The present disclosure is directed to non-aqueous, curable film-forming compositions comprising: a) an anhydride functional compound; b) an aziridine functional compound; and c) a hydroxyl functional compound different from a) and b) and having at least two hydroxyl functional groups. The present disclosure is further directed to methods of preparing coated substrates with these compositions, an exemplary method comprising: (A) optionally applying a primary film-forming composition to at least a portion of a surface of the substrate to form a first coating; (B) applying the curable film-forming composition directly to at least a portion of a surface of the substrate or to at least a portion of the first coating formed in step (A) to form a coated substrate; and (C) subjecting the coated substrate to curing conditions, whereby the curable film-forming composition undergoes multiple cure reactions.
