Résumé : |
A bio-based, solvent-free, low-viscosity, polyester polyol was prepared from raw material that can be either 14C or mass-balance certified. The basic properties, such as OH number, viscosity and Tg , are a close match to the ones of a petrol-based resin that is often used as a modifier of high-solids acrylic polyols in 2K PU topcoats or DTMs or as a stand-alone binder. This novel polyester polyol represents the next step towards sustainable coatings. |
