| Résumé : |
Resin and paint producers are under increasing pressure to find environmentally friendly alternatives to conventional solvent-borne polyurethane for protective topcoats. We have developed easy process to produce high-performance solvent-free water-borne acrylic polyols via primary or secondary dispersion using glycidyl neodecanoate or its acrylated adduct. |
