Dispersing agents

Dispersing agents are interface acting substances, which facilitate the dispersion of a substance in powder form, e.g. a pigment or thickener, in a fluid medium. They reduce the interface tension between the contrarily charged components by reloading the surfaces. Thus, in the dispersion process, the agglomerates are broken up and permanently reduced to primary particles, so that re-agglomeration or flocculation (the forming of hard or soft lumps) are prevented and the necessary storage stability of paints and other coating substances is guaranteed. Dispersing agents are used in dispersion paints, ceramics, adhesives, paper-coatings etc, in order to increase the speed of production and storability. Our dispersing agents have both a stabilising and a dispersing effect. Essential for this is ionisation in water. They can be mixed with water in any proportion. All the dispersing agents in this range are non-viscous fluids that are easy to handle.
For the dispersion of inorganic and organic pigments on basis of PU and Polyacrylates we offer both for aqueous- and solvent lacquers a broad spectrum to prevent flooding, floating and hard-settling. In addition for all industrial lacquer systems special wetting and dispersing agents with controlled flockulation are recommended.
