Several waterborne acrylic resin/polyester polymer blends were used for grinding pigments (e.g. millbases) for different applications such as waterborne inks, coatings and paints. Commercially available pigments contained mostly acrylic resins as a grinding vehicle.
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.
