How to disperse and stabilize pigments

Grinding Medium Anchoring of the polymeric dispersant to the pigment surface can be affected by competition between the resin and dispersant for the surface of the particle. Once the anchor group of the dispersant is attached to the pigment surface it will remain firmly attached.

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 liquid. Typical Hegman dispersion is 7 – the exact meaning of the Hegman scale will be discussed in further detail.
