March 4, 2020 For years, color coatings manufacturers have been using highshear mixing techniques to try to wet pigments and reduce particle sizes in raw materials before wet milling. The theory is clear. The smaller the bead you can use in the final milling process, the less massspecific energy is required to create a quality color dispersion.

The Fine Impact Mill Condux 680 with pin disc counter rotating design. (Source: Netzsch) ... A more efficient milling can thus result in a more intense pigment by improving the dispersion of the pigment in the coloured material. In addition to this, the specific size and shape of particles give a particular appearance to the surface. ...

Pigment Dispersion: A Quick Definition for Busy Paints Inks Formulators Pigments and fillers are powdery materials consisting of insoluble solid particles. In the powdery dry state, the solid particles are surrounded by air. Separated solid particles in liquids tend to flocculate, creating lumps.

The dispersion of pigments in printing inks is impor tant for several reasons as it improves the color strength of pigment, increases the transparency of pigment, affects rheological behavior and flow prop erties of the ink, provides more gloss and finally, it provides stability to ink throughout its shelf life (Pal and Fleming, 2006; Simpson,...

The pigment dispersion process involves replacing airsolid interfaces in the dry powder with liquidsolid interfaces and separating the clumps of pigment particles so that they are dispersed in the liquid. The dispersed particles must be separated, or they will flocculate to form new clumps.

The dispersion process. The various processes which occur during pigment dispersion can be divided into the following three steps: During Step 1, all of the air and moisture at the pigment surface is displaced and then replaced by the binder solution. The binder solution wets the pigment particles and the solid/gaseous interface (pigment/air ...

A typical raw material ratio is 20/30% wax, 50/70% grease and 5/15% pigment. In the first stage, the pigment needs to be mixed with an appropriate amount of oil (the ideal ratio of pigment to oil is two parts oil and one part pigment), and then the mixture is ground with a three roll mill to uniformly disperse the pigment polymer.

What is Bead Milling? Bead Mills are machines for dispersion processing, where solid particles (pigments, fillers) are reduced in size and finely dispersed and wetted out in a liquid phase. Small ceramic, glass or metal beads are agitated inside the mill chamber to aid particle size reduction through impact and energy input while the dispersion ...

Pigment dispersion. Pigments are usually incorporated in the coating in the form of dry pigment powders. The pigments are not primary particles, they are agglomerates. Agglomerates represent pigment "groupings" in which the spaces between the individual pigment particles contain air and moisture. These individual pigment particles are in ...

Many readers will know that the dispersing of pigment involves three steps: wetting, deagglomeration, and stabilization. Good wetting depends on the dispersing medium (solvent, resin solution, or surfactant dispersion) being compatible with and having a lower surface tension than the pigments.
