Optimizing Dispersant Levels for Waterborne Pigment Color Concentrates
This article presents a method to reduce the time required to screen dispersants for efficacy, and emphasizes the need to optimize dispersant concentration.
Recent publications have labeled copolymeric dispersants as “high molecular weight” (HMW) and other low-molecular-weight dispersants as “traditional.”2-4 The exact molecular weights of commercial HMW dispersants are proprietary, but the literature has focused on the molecular weight differences to distinguish HMW dispersants from traditional dispersants.
