Dispersing agents | Arkema Rheology & Specialty Additives

Dispersing agents are used to disperse and maintain the stable state of dispersion of mineral and/or organic particles suspended in liquids.

Their use is of great value in the mineral industry, paper and board coating, paint and coating or detergents formulations as well as clays for ceramics, to improve dispersion stability of fillers and pigments.

Different technologies to meet various needs

The role of dispersing agents is to adsorb onto the surface of pigment/filler particles to create repulsive forces.

These forces keep the particles apart and reduce their tendency to flocculate. This is achieved by means of electrostatic repulsion with anionic dispersants and/or steric stabilization with steric dispersants.
