Pigment Dispersion Troubleshooting Guide Why Pigment Dispersion Viscosity Increases During Storage—and How to Fix It Pigment Dispersion Viscosity can remain stable immediately after milling but increase after several days or weeks of storage. Reflocculation, insufficient pigment stabilization, pH changes, rheology development, temperature and additive interactions are among the areas formulators should investigate. Technical Troubleshooting Pigment […]
Pigment Dispersion Technical Guide Dispersant Dosage Optimization: How to Find the Right Level for Pigments Dispersant Dosage Optimization is essential for controlling pigment dispersion viscosity, color development, gloss and storage stability. Too little dispersant can leave pigment surfaces insufficiently stabilized, while unnecessary excess may increase cost or affect other formulation properties. Technical Guide Dispersant Dosage […]
