High-performance wetting and dispersing agents

The wetting and dispersing agents from Nordmann partner Nouryon ensure excellent wetting and stabilization of pigments. They are used in the paint and coatings industry and for the production of pigment preparations (aqueous, solvent-based and universal). 

All pigments, whether organic or inorganic, consist of primary particles that aggregate to form larger particles. These aggregates can easily form larger units known as agglomerates. During dispersion, the agglomerates are broken up by applying mechanical energy and distributed in a liquid medium. The wetting agents enable rapid wetting of the agglomerates with the liquid medium. The dispersing additives in turn stabilize the pigment dispersion. The same additives often fulfill both functions. However, combinations of additives are also used, for example to improve pigment wetting, stabilization and compatibility.
