Résumé : |
High requirements converning environmental protectionare the reason for an increased interest in low VOC coatings technologies. One strategic route is the development of waterborne coating systems. Due to versatility, aqueous polyurethane dispersions (PUD) are of special interest. The various processes for the synthesis of solvent free PUDs which includes ketazine process, melt dispersion process, acetone and NMP processes have been described in details. Alternative solvents to NMP replacement in polyurethane synthesis have been elaborated. Comparative study of NMP and acetone process has been described and how the composition parameters play the key role in the synthesis of a low VOC or zero VOC PUD. |
