Pigment wetting: The air and moisture covering the pigment is replaced by the resin solution. The solid/gas interface (pigment/air) is transformed into a solid/liquid interface (pigment/resin solution). Grinding stage: By high shear forces the pigment agglomerates are broken up into smaller units, preferable primary particles. Stabilization: The pigment dispersion is stabilized …

Grinding media with a smaller diameter have a positive effect on the dispersion of pigment blacks, although their separation and cleansing are more difficult to achieve. In the experiments that will be described later, grinding media with diameters from 0.6-0.8 or 1.6-2.0 mm were used.

The process of the present invention produces an aqueous dispersion of mineral materials, suitable for use in pigments and other coatings, by introducing a fully neutralized dispersing agent to an aqueous dispersion of coarse mineral materials, grinding the aqueous dispersion and, during grinding, adding a partially neutralized dispersing agent to the aqueous dispersion.

Ball milling is a grinding technique that uses media to effectively break down pigment agglomerates and aggregates to their primary particles. Using a rotor or disc impeller to create collisions of the grinding media, the impact and force created by the bead mills collisions break down the pigment agglomerates.

Pigment dispersion can be divided into three overlapping steps: Wetting—for good wetting, the dispersant must have a lower surface tension than that of the pigment. This enables the dispersant to displace air and water from pigment surfaces and penetrate pores, gaps, and channels between particles and adsorb onto them.

These "grinding media" combine the advantages of selective drying capacity, crosslinking into the film, anti-settling and anti-floating effect and compatibility to both solvent-borne and water-borne systems. Such novel "grinding media" can be used to produce highest quality pigment pastes for Automotive OEM

Apart from being strongly adsorbed at the surface of the solid particles, the dispersant has to give colloidal stability. Dispersion is said to be stable from colloidal point of view when flocculation of separated particles is prevented because the particles repel each other. *Functional groups, such as amine, amides, sulfonate, phosphate, for firm anchoring onto pigment surfaces are present ...

Allow the pigments to be extraction for 2 hr in total darkness. Dilute acetone extract with 1 mL absolute methanol and 1 mL H 2 O. Measure absorbance of DMSO extract at 665, 631, 582, and 480 nm. Measure acetone extract at 664, 631, 581, and 470 nm. NOTE: Use 4:1 DMSO:H 2 O and 3:1:1 Acetone:Methanol:H 2 O as blanks.

Composition of pigment concentrates . The key component of a pigment concentrate is the pigment; the pigment content should be as high as possible.In addition, a grinding resin is required in most cases in order to obtain a storable paste and to ensure that the paste can be easily incorporated in the finalizing binder without any shock phenomena. The grinding paste …
