pigment dispersion and the color devel-opment properties of a pigment, includ-ing the opacity and transparency, has been noted for some time by Mie. 21 Later, Brockes 22 and Chromey23 applied spe-cifically to pigments of all shapes Mie's theory of spheres. The Mie theory states that for a given pigment, maximum color development is achieved ...
This mixture was well dispersed under ultrasound (JP-030S, Jiemeng, China) for 5 min, then transferred to an all-round planetary ball mill (QM-QX2, Nanjing, China) filled with 1.2 mm ZrO 2 balls (mass ratio of ZrO 2 to pigment was 150:1). The mixture was dispersed for 10 h to get the predispersed pigment dispersion. 2.2.2.

Continuing August's article on pigment dispersion, this article will cover high-speed dispersion. As a younger formulator 20-plus years ago, I attended a presentation on "Practical Paint Making" by George Goodwin. I learned a lot that day and wish to thank him for taking the time to pass on his knowledge.
In the quest of ensuring successful pigment dispersion, additives are used to aid dispersion and stabilization of pigment particles through attraction forces of various chemical nature including van der waals and "liquid bridge" forces as well as anchor groups with high affinity for pigment surface. On the other hand, dispersion efficiency ...

This Second Edition contains new chapters on pigment/binder geometry, theoretical aspects of dispersion, and capillarity. Covers: viscosity and viscosity measurement, …
Stabilization of a pigment dispersion requires time and energy. Dispersed pigments have a strong tendency to return to their initial agglomerated state. Due to this strong ... 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
Pigment Dispersion Part 2. Gebruder Netzsch announce a new bead agitator ball mill, called the Netzsch LM mill. It is a continuously operating mill with a horizontal position grinding chamber. The main purpose of this development was to first of all design a separator that would successfully separate beads as small as 0.25 mm dia from the ...
