The degree of pigment dispersion affects color strength, gloss, brightness and transparency, as well as the rheological properties of the system. These properties are governed by the size and distribution of the pigment particles in the system.1 Pigment dispersion can be divided into three phases – initial wetting, breaking of aggregates and agglomerates, and flocculation. However, the three phases are not always taken into consideration by pigment users; consequently, a pigment is frequently described as ‘poor in dispersion properties’, regardless of the specific phase in which it is actually deficient.”2
