ABSTRACT
The dispersion of pigments in fluid media is of great technological importance to the coatings manufacturers who deal with pigmented systems. The basic aim is to change the physical state of pigments to achieve desired effects in specific application systems. The dispersion process involves the breaking down and separation of the aggregated and agglomerated particles that are present in all pigments in their normal form after their manufacture. Dispersion is not considered to be a process of pulverization but rather a process of particle separation, homogeneous distribution of the particles in a medium, and stabilization of the resultant system to prevent reaggregation, reagglomeration, flocculation, and settling. The process of dispersion must be done efficiently and in the shortest time possible to draw out of the pigment its maximum color properties at the least cost.
