Perspective: green polyurethane synthesis for coating applications

Polyurethanes exhibit excellent coating properties for many applications. Facing the continuous growth of the polyurethane coating market, in the last few years many scientists have addressed the safety and sustainability of their production. This paper highlights the efforts that have been pursued in this direction from both the academic and industrial perspectives and covers aspects ranging from the substitution of petroleum-based monomers by biobased equivalents to the development of novel synthetic pathways for the production of polyhydroxyurethanes.
