Abstract
This invention discloses an approach of achieving bio-based carbon negative topcoats by developing a plant-based non-isocyanate polyurethane coating. Both bio-based contents and carbon dioxide are used as feeding materials in resin synthesis and formulations, yielding durable topcoats with low environmental footprints.
