Abstract
Polyurethane (PU) coatings have a wide demand in industry and are used for the protection of metal, concrete and wood structures. However, PU coatings face challenges in regard to circular economy concepts. Although waterborne solvent formulation techniques as well as naturally derived monomers are compatible with a circular economy, PU coatings possess a strong barrier. In this study, a series of PU coatings were prepared using water as the main solvent, and the polyol and chain extender monomers used were prepared from natural resources. The synthesized PU coating showed UV resistance, fire retardancy and corrosion protection. The exposed PU coating was collected and used with Portland cement.
