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.

Our products for the preservation of mineral suspensions and slurries



  • Liquid preservative based on 1,2-Benzisothiazolin-3-one (BIT) and Tetramethylolacetylenediurea (TMAD).
  • For the preservation of aqueous technical preparations such as aqueous coatings, plasters, polymer dispersions, synthetic adhesives, pigment slurries, concrete additives or cleaners and detergents.
  • The product has a broad spectrum of activity covering bacteria (aerobic and anaerobic), mould and yeasts. The often slow onset of action of benzisothiazolinone is accelerated by the added TMAD, particularly in the case of bacteria.
