Mineral Suspensions/Slurries

Slurries composed of calcium carbonate, kaolin, and other organic or inorganic pigments are often a particular preservation challenge because of such factors as high temperatures during grinding or high pH values. LANXESS products make it possible to effectively prevent the growth of bacteria throughout production and during both storage and transport.
