Pokraskin The dispersion properties are determined with an automatic muller. The advantage is that small amounts of material can be simply tested under reproducible conditions. For standards, see Table 1.1 (“Ease of dispersion: Automatic muller”).
Development of Fineness of Grind
The quantity measured is the dispersing effect needed to achieve a given fineness of grind. Samples of the product are taken at various stages of the dispersion process and the fineness of grind is determined with a grindometer gauge. The method is used to compare diverse millbase material types of dispersing equipment, or dispersing methods used with the same pigment. For standards, see Table 1.1 (“Fineness of grind”).
