How to disperse and stabilize pigments
The solid/gaseous interface (pigment/air) is transformed into a solid/liquid interface (pigment/resin solution). Grinding stage: Through mechanical energy (impact and shear forces), the pigment agglomerates are broken up and disrupted into smaller units and dispersed (uniformly distributed).

Determining the optimal dispersing agent loading
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).

The importance of wetting and dispersant surfactants in
01/04/2021 In the dispersion/grinding stage, the pigment clumps are mechanically separated into smaller particles. The wetting and dispersing surfactants act synergistically, to ensure that the wetting of the smaller particles created happens faster and the particles do not clump again, so reducing process time and, consequently, energy spent. The proper choice of a wetting and dispersion surfactant

05/08/2021 Grinding of pigments. This is achieved by using mechanical dispersing units. By high shear forces the interaction of the individual particles is resolved and thus the wetting of the particles is supported resulting in separation of the agglomerates. This stage is very susceptible to new agglomerations first and therefore it is important to stabilise it at once. Stabilisation of the dispersion
