Pigments are powders that provide colors for materials such as paints, coatings and inks. Those are very important parts in them. They can be organic or inorganic and are often finely ground powders that are mixed with a medium to create a uniform color.

Pigment dispersion refers to the process of evenly dispersing small particles of pigments in a liquid medium, such as water or oil, to create a stable and uniform colorant. Pigment dispersions are commonly used in a variety of applications, including paints, coatings, inks, and plastics.

The dispersion process involves breaking down and separating the pigment particles to prevent agglomeration or settling, which can lead to uneven coloration and poor performance. This is typically achieved through mechanical methods such as milling, high-speed mixing, or ultrasonic agitation.

Once the pigment particles are uniformly dispersed in the liquid medium, they can be further processed or used directly to color a variety of materials. Pigment dispersion is an important step in achieving high-quality and consistent color in many industrial and artistic applications.

Wetting:

The liquid mediums spread on the surface of pigment particles and remove water and air entrapped by stirring. Micro-molecule wetting additives can help to enhance wetting

Dispersion:

The pigment agglomerates are broken up into primary particles under shear force.

Stabilization:

Separate the finely dispersed pigment particles to prevent from flocculating. Macromolecule dispersant works more efficiently on stabilization.
