Drying, film formation and open time of aqueous polymer dispersions

Industry has invested significant time and effort to develop water-based paints and varnishes, that show a drying behaviour comparable to that of established solvent-based polymer solutions. To further improve the application properties - open time, film quality and compound distribution - of water-based formulations, it requires a fundamental understanding of the drying and film formation mechanism from colloidal dispersions. This is where this work wants to make a contribution using experimental data and model calculations.
