Competitive waterborne chemistries such as water-reducible alkyds, alkyd dispersions, poly-urethane dispersions, and waterborne epoxies and epoxy-esters could not compete with acrylic latex technology for stability, price, solids content, or a combination of these factors. Although alter-nate waterborne chemistries will never satisfy the

Fine Grinding Of Carbon Black | Ink World
Typical high-speed dispersing with a sawtooth blade rotating at a shear rate of 600-800 sec-1 begins to de-agglomerate pigment particles. But for fine grinding of carbon black, high-speed dispersion does not completely de-agglomerate the particles. This is the purpose of the bead mill. The bead mill works like a filtering system.

Pigment Dispersion
Pigment dispersion is the process of suspending insoluble pigments in a liquid medium, typically water or organic solvent, so that they can be used in inks paints and coatings. Traditionally, pigment dispersion is comprised of three main steps; wetting, deagglomeration, and stabilization. These three steps are outlined in further detail below.

High electrical conductivity waterborne dispersions of carbon black pigment
The milling chamber of the bead mill has an empty volume of 50 mL and it needed to be filled between approximately 65% (32.5 mL) and 85% (42.5 mL) with grinding beads. The size of the zirconium oxide beads used as grinding media was approximately 1–1.25 mm and the bead loading was maintained between 30–35 mL.
