form of dispersion to carry the color into a product. For these applications, concentrated colored pastes are used. Colored pastes are made by grinding colored pigments into a liquid carrier on a 3-roll ink mill. An ink mill uses very tight clearances to crush the pigment aggregates to a fine dust, which is then dispersed in the accompanying ...

PIGMENT DISPERSIONS Both organic and inorganic pigments were dispersed in the PUD XM-231118. The pigment is dispersed in the PUD additional water or amine is added and the paste is dispersed. The carbon black is ground in a steel ball mill for 24-72 hours depending on the degree of jetness and dispersion desired. The organic pigments were dispersed

The dispersant may be a polymer solution (possibly of a surfactant-like polymer), a surfactant solution or dispersion, a solvent or a combination of these. Wetting agents often are added to reduce interfacial tension and improve initial formation of the liquid-solid interfaces. The resulting dispersion commonly is called a pigment paste.

During this time, the polymers must melt, pigment disagglomeration must be achieved and all raw materials must be homogeneously distributed. If we compare this with liquid coating manufacture by ball-milling, high speed dispersion or sand-milling, which involves hours of dispersion time to achieve disagglomeration and wetting, it is obvious that
