| Résumé : |
A unique dynamic fingerprint of any ink formulation can be generated in terms of surface tension versus surface age, from zero time to several minutes, using a differential maximum bubble bubble pressure technique. This allows formulators and users to characterize ink performance under all possible conditions before the ink is used.When multiple surfactants are used, the unique surface tension fingerprint may not be a "classical" dynamic curve, as different surfactants diffuse to the interface at different rates, resulting in a more complexe dynamic curve with several peaks and valleys. In some cases, the lowest surface tension formulation may not be the best one to use, because it can cause other problems. |
