Linear and branched bio-based semi-aromatic (co)polyesters were evaluated as resins for solvent-basedand powder coatings. Dimethyl-2,5-furandicarboxylate (DMF), 2,3-butanediol and various multifunc-tional comonomers were used to synthesize amorphous hydroxyl-end-capped (co)polyesters. The resinswere cross-linked using the -caprolactam blocked trimer of isophorone diisocyanate. Both the solvent-based and powder coatings proved to be hard but brittle, which was a result of the very stiff molecularstructure of the formed network. This was corroborated by the Tgvalues obtained for the coatings, whichexceeded 100◦C for both the solvent-based and powder coatings. The poly(ester urethane) coatings pre-pared from the branched copolyesters show a reasonable solvent resistance. However, swelling occurredduring the solvent treatment, indicating an insufficient network formation. The solvent-based and pow-der coatings exhibit similar mechanical and physical performance, showing that in this study there wasno significant influence of the preparation method. In view of the obtained results it can be concludedthat DMF-based branched polyesters are interesting candidates for solvent-based and powder coatingapplications.
