How to disperse and stabilize pigments

Pigment wetting: All of the air and moisture is displaced from the surface and between the particles of the pigment aggregates and agglomerates (clusters) and is replaced by the resin solution. The solid/gaseous interface ( pigment/air) is transformed into a solid/liquid interface (pigment/resin solution). Grinding stage:.
