Dispersants for wet milling


Improved dispersion in the manufacturing process of pigments, fillers, and flame retardants.


Our TEGOMER® dispersants applied in the water-based manufacturing process of fillers, pigments, and flame retardants reduce the viscosity of the slurry and enable a high loading of fine-sized particles in the filter cake. Reduced water content in the filter cake requires less drying capacity, allowing manufacturers to save valuable energy while achieving a high-end dispersion of the pigment, filler or flame retardant. 


  • TEGOMER® DA 640

    TEGOMER® DA 640 is an anionic modified polyether to be used for the following main applications:

    • dispersing of fillers as well as of inorganic and organic pigments in water-based systems
    • flocculation of inorganic pigments or fillers even in presence of high electrolyte content
    • emulsifier for the polymerization

  • TEGOMER® DA 646

    TEGOMER® DA 646 is a wetting and dispersing additive based on polyether technology and can be used as dispersant in liquid or solid concentrates. Furthermore TEGOMER® DA 646 is an emulsifier technology to replace APEO in polymer dispersions.

  • TEGOMER® DA 850

    TEGOMER® DA 850 is a polymeric copolymer with pigment affinic groups to be used as a dispersant in water based-surroundings. It allows to transfer water-based pigment slurries into thermoplastics when water is being evaporated during the extrusion process.
