摘要： The present application relates to a two-component polyurethane coating composition, a coating formed from the two-component polyurethane coating composition and a coated article. The two-component polyurethane coating composition comprises: component A comprising an aqueous dispersion of at least one hydroxyl functional resin; and component B comprising at least one non-hydrophilic isocyanate curing agent and at least one diluent, wherein the at least one diluent comprises at least one alkyl glycol ester, at least one cyclic carbonate ester, or combinations thereof, and the at least one alkyl glycol ester does not have an ether bond. The coated article of the present application comprises the coating formed from the two-component polyurethane coating composition. The coating composition of the invention adopts a low-cost non-hydrophilic curing agent, and the formed coating has improved gloss or transparency.
