pigment grinding agent

Determining the optimal dispersing agent loading - li

The idea of wet grinding probably originates from the way many pigments are made.When the pigments are precipitated they are kept damp called `the pigment cake`. This is to prevent much of the agglomeration (forming lumps and larger particles).It is ground wet,sometimes with added surfactants etc...

Pigment Dispersion I, The Basics - American Coatings ...

This enables the dispersant to displace air and water from pigment surfaces and penetrate pores, gaps, and channels between particles and adsorb onto them. Wetting agents often are used to facilitate this process. Another strategy is to modify the pigment surface to make it more wettable and, therefore, more easily dispersed.

Pigments / Dyes - NETZSCH Grinding & Dispersing

Pigments are made up of particulate matter that is insoluble in its vehicle and therefore must be finely dispersed in a binding agent. Due to their optical properties they are used as chromophoric substances, for example in paints, inks or Inkjet inks or, thanks to special technical and chemical properties, as anticorrosive agents for example.

A black single coat formulation utilizing PUD XM-2311 as a pigment grinding agent, PUD XM-4316 as a backbone resin and HMMM as a crosslinker is shown in Table 9. To prepare the pigment paste the XM-2311 polyurethane dispersant resin is blended with water and dimethyl ethanolamine and the carbon black is added. This

Pigment Dispersion: Wetting & Dispersing Agents for Coatings

Dispersant or dispersing agent is defined as a surface-active chemical that has a solvating action on the solid particles (pigments or fillers) to be dispersed and thus promotes formation of dispersion by dispersing or suspending them. Dispersants help maintain a state of dispersion by preventing settling or aggregation.

Wetting and Dispersing Additives - BYK

Wetting agents are surface-active substances and improve the wetting of solids. Dispersing agents prevent particles flocculating by various mechanisms (electrostatic effects, steric effects). Wetting and dispersing additives unite both mechanisms of action in one product, i.e. they are both wetting and stabilizing.

FEATURE Four Steps to Effective - pigments

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 deagglomerated need to be stabilized in order to avoid issues such as flocculation, color shift, sedimentation and stability loss.

Determining the optimal dispersing agent loading - li

1). Prepare the pigment slurry – Pigment content is high enough, such that a slurry is obtained after mixing in the absence of a dispersing agent. Usually, a loading of 30 wt.% for organic pigments, or 55 wt.% for inorganic pigments, is necessary. Dispersing time is about 30 minutes with a dissolver (or equivalent). 2).
