It involves preferential displacement of gases, liquids and other contaminants from the surface of the pigment with the grinding medium.(2) The dispersing agent can assist greatly in this process by acting to form the direct …
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 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.
process. The basic formulation of ink involves the grinding of pigment in a vehicle to form the pigment dispersion, then letting down the pigment dispersion with suitable resins to meet rheological and functional properties. The main components of water-based inks are pigment, binding agent, carrier (water) and additives.
Dispersogen® PLF 100 is a dispersing agent that offers a reliable solution to these challenges.In our tests, paints formulated with our product clearly exhibited lower ing during grinding and smaller viscosity changes during storage than paints prepared with the market alternatives.
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.

The grinding process can be regarded as a de-flocculation process. In the absence of stabilizing agents, effects such as reduced color strength, decreased gloss, and altered rheology then may occur.

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...

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).
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.
Special grinding medium for OEM basecoat systems. Request sample: ADDITOL ® XL 270: ADDITOL ® XL 270 is a highly efficient pigment wetting agent that enables improved viscosity of your coatings at low shear forces.
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.
Grinding Resin For solvent-borne pigment concentrates, grinding resins based on acrylates, aldehydes, ketones, polyesters and alkyds are commonly used. Special attention is required in terms of the possible negative impact of the grinding resin on film properties of the final coating. Grinding resins in water-borne systems show a stronger ...
