GCC suspension behaviour and rheology GCC slurries and their response in coating colours Slurry suspensions of GCC are the preferred product form. Stability of dispersion in slurries is achieved using polymeric dispersants, usually derived from polyacrylates or polyphosphates having an anionic surface charge. In some special cases, such as pigments for inkjet coatings, the dispersion
