Abstract: A coating, system comprises 30 to 90 parts by weight of a bioresin component and 10 to 70 parts by weight of an isocyanate component, based on 100 parts by weight of the coating system, and has a percent solids of greater than 60%. The bioresin component comprises an acrylic polymer and a biopolyol formed from a natural oil. A method of forming a coating on a substrate with the coating system comprises the steps of combining the bioresin component and the isocyanate component to form a reaction mixture having a percent solids of greater than 60 percent, applying the reaction mixture onto the substrate, and curing the reaction mixture to form the coating on the substrate.
