/Coating Compositions
Abstract

The present invention is directed to compositions comprising a first component, a second component, and elastomeric particles. The first component comprises an epoxy-containing compound. The second component comprises a diamine comprising a cyclic ring and/or a polyamine comprising a cyclic ring. The diamine may chemically react with the epoxy-containing compound. Optionally, the cyclic ring of the diamine and/or the polyamine has at least one carbon positioned between the amino functional groups and the cyclic ring structure. Optionally, at least 50% by weight of the elastomeric particles comprise a styrene butadiene core based on total weight of the elastomeric particles. The present invention is also directed to methods of making the compositions, methods of coating a substrate, and coated substrates.
