Abstract:
Disclosed is an epoxide-functional adduct (E2) and an amine-functional adduct (A3) and coating compositions including these adducts. The epoxide-functional adduct (E2) comprises a reaction product of a reaction mixture comprising (a) an epoxy-containing compound (E1) and (b) a diamine comprising a cyclic ring and/or a polyamine comprising a cyclic ring (A1). The amine-functional adduct comprises a reaction product of a reaction mixture comprising the epoxy-functional adduct (E2) and a monoamine, diamine, and/or polyamine (A2), wherein the monoamine, diamine, and/or polyamine (A2) are different than the diamine comprising a cyclic ring and/or the polyamine comprising a cyclic ring (A1). The present invention is also directed to methods of making the compositions, methods of coating a substrate, and coated substrates.
