| Résumé : |
With the EU Green Deal targeting climate neutrality by 2050, the need to reduce the environmental impact of industrial processes like wood coatings is increasing. Using tools like the life cycle assessment (LCA), we demonstrate how water-borne polyurethane systems can help us to reduce the carbon footprint of wood coatings in comparison to two component solvent-borne polyurethanes. We highlight the latest developments, such as a hardener ("Bayhydur quix") which can additionally contribute to a significant reduction of the environ-mental footprint in a high-performance wood coating system by accelerating the drying process. We also present different available solutions for further reducing CO, emissions by using partially bio-based raw materials, both for solvent-borne and water-borne technologies. |
