Abstract
An acrylic composition includes the reaction product of an acrylic polymer, a carboxylic acid compound, and an alkyl carbamate. The acrylic polymer includes the reaction product of a functionalized monomer, a first compound reactive with the functionalized monomer to form a functionalized intermediate, and a highly branched, polyfunctional core molecule reactive with the functionalized intermediate. The first compound includes vinyl functionality reactive with the functionalized monomer and epoxy functionality. The carboxylic acid compound has carboxylic acid functionality that is reactive with the acrylic polymer. The alkyl carbamate is reactive with the hydroxyl-functional acrylic polymer to form the acrylic composition. The acrylic composition is highly-branched and, when used in coating compositions in combination with a suitable cross-linking agent, enhances recoat adhesion and produces cured films that have optimum scratch, mar, and chip performance, and acid etch resistance.
