Pigment paste is a type of monopigmented system that contains a high concentration of pigments and a small amount of binder (grinding resin). It is used in the production of coatings in two ways: for tinting and for production.

For tinting, pigment pastes are used for the final fine adjustment of the color, i.e., for nuancing. In this case, only a small percentage of the pastes are used. The individual components of the pigment concentrates (especially the grinding resin) then have virtually no obvious influence on the quality of the coating that has been tinted.

For production, a coating can be made up entirely of a blend of pastes and then let down with the desired binder (as a clear coating or white coating). Greater quantities of pigment pastes are required for this. As the pastes then have a significantly greater influence on the coating quality, the requirements on the quality of the pigment concentrates are also considerably greater.

Pigment pastes are used to provide color to various products such as paints, inks, and plastics. They are made by dispersing pigments in a liquid medium with the help of wetting agents and dispersants. The resulting dispersion is commonly called a pigment paste
