A renewable and multifunctional eco-friendly coating from novel tung oil-based cationic waterborne polyurethane dispersions

Bio-based waterborne polyurethanes (WPUs) as a novel kind of economic and eco-friendly coating have attracted more attention in recent decades due to their sustainability, availability, and low toxicity advantages. In this work, a tung oil based polyol (TOP) is effectively fabricated without complicated purification process under a relative low reaction temperature, and subsequently used to prepare a series of cationic waterborne polyurethane...
