Stephen Istivan - Formulation of Waterborne Pigment Dispersions


Formulation of Waterborne Pigment Dispersions

Color pigments are one of the most expensive ingredients for coatings and thus need to be fully utilized by grinding and then imparting colloidal stability against flocculation.  Colloidal stabilization mechanism for waterborne pigment dispersions is quite different from that for  solvent-borne pigment dispersions.  In this short course, we will discuss in details colloidal stability in waterborne systems and then learn how to select pigments, dispersants and cosolvents.  We will also learn how milling procedures affect colloidal stability.
