    Research output: PatentPatent


    According to an example aspect of the present invention, there is provided a dispersant comprising alkaline-O2 oxidized lignin. Such dispersant may be used for example in inorganic pigments to reduce interactions between pigment particles and lower the viscosity of pigment mixtures, and thereby positively affect for example to the loading of fillers and pigments in paints and coatings, paper and board, constructions materials, printing inks and plastics. Dispersants may also be used in aiding the inorganic pigment grinding in the pigment mine. Another suitable use is as a plasticizer or as a retardant agent for construction materials, such as gypsum.
