Develop Your Colors to the Fullest Novel Dispersants for Optimum Pigment Dispersions

摘要

Engineering polymeric dispersants to maximize dispersant-pigment interaction with PR 179 and high jet carbon blacks has proven to positively impact not only color development of the pigment, but equally important the viscosity and viscosity stability of the grind. While reducing the mean particle size of the grind through longer milling process improves color strength, it is not the only determining factor for good color development. Pigment surface wetting and stabilization of the finely dispersed particles are crucial in delivering the desired hues and jetness. Optimizing such interaction will enable formulators to create stable dispersions with less milling time and allow for color and process optimization.
