Coating compositions include a crosslinker and a hyperbranched polymer and methods of producing coating compositions include combining a crosslinker and a hyperbranched polymer. Branching portions of the hyperbranched polymer include a linkage via a carbonyl group and at least two linkages via methylene groups. Branching compounds used in a process to form a hyperbranched polymer include at least one hydroxyl group and at least two oxirane groups. Resulting hyperbranched polymers can include dendrimers. Coating compositions having hyperbranched polymers and crosslinkers can be applied to a substrate and cured to form a crosslinked film.
