    Abstract: Disclosed herein is a composition comprising: an epoxy-containing component, elastomeric particles in an amount of greater than 11% by weight to 25% by weight based on total weight of the composition; and a curing component activatable by an external energy source, the curing component comprising at least one guanidine having a D90 particle size of 25 μm measured by dynamic light scattering. Also disclosed is the composition in an at least partially cured state. Also disclosed is a method for treating a substrate comprising applying the composition to a surface of a substrate; and applying an external energy source to cure the composition. Also disclosed are substrates comprising the composition. Also disclosed are substrates formed by the method of the present invention.

    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.
