grinding of pigment. Generally, high viscosity dispersions are not easy to grind using a lab-scale re-circulating bead mill. There are numerous factors that can potentially result in changes in the starting point formulations. It is therefore crucial to assess any variations in the pigment loading occurring during milling for extended time periods.

dia mill, which produces significantly more shear, such as horizontal, vertical and basket mills. In order to disperse the pigment to a nano level, the use of 0.3-0.5 nm grinding media is recommended. Stabilization Due to the increased surface area of the solid particles dur-ing the deagglomeration/grinding stage, the pigments that are
More specifically, a mill, such as a ball mill, grind mill, or continuous mill, is utilized to incorporate the pigment into the grind resin. The mill integrates the pigment into the grind resin until a desired particle size of the pigment is achieved, and until the pigment is appropriately wetted by the grind resin and uniformly dispersed ...
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. These pigments usually exhibited a limited applications with polyesters, when ...

All pigments were ground for at least an hour by a bead mill, and all pigment tints achieved fineness of grind readings of 2.5 µm or better at the end of grinding. The tinting strength of all non-white pigment concentrates was evaluated using a white-base formula W-Base (Table 3), which was based on Polyol 6810.

Composition of the pigment paste made up for subsequent testing of dispersion quality. After grinding, clear lacquers are pigmented with the prepared tinters and applied onto clean glass plates. The ratio of the pigment to binder solids should be as follows: Inorganic pigments = 20-30%. Organic pigments = 10-15%. Carbon black = 5-10%. 3).
Disc sand mill is the mainstream equipment for grinding and dispersing pigments.

In the industry, the fineness of grind is generally achieved with a 2-step process. First, developers and producers of paints use a dissolver to reduce the particle size of their pigments and fillers to a certain degree of fineness. Then, when needed, they additionally use a pearl mill to further separate the solid particles from each other.
