Advantages of Rheology Modifier Clays


BS-1C-FF is an organo-clay for solvent-based systems of low to medium polarity.


  • High gelling efficiency over low and medium polarity organic liquids
  • High viscosity and excellent thickening property over a wide temperature range.
  • Imparts particle suspension, preventing hard settling of pigment and fillers.
  • Ideal thixotropy property and anti-sediment property.
  • Exerts strong film reinforce action in organic binder systems

Typical Properties

Color Appearance Density Moisture (@105℃,2hrs) Mesh Size (200 mesh) Loss on Ignition (@1000℃)
Light Yellow Free Flowing Powder 1.75g/cm3 ≤3.5% ≥97% ≤33.0%


Typical Applications

  • Adhesives and Sealants
  • Anti-Corrosion Paints
  • Container Paints
  • Bituminous Paints
  • Printing inks
  • Lubricating grease


BS-1C-FF belongs to the conventional type of organo-clay group, which requires mechanical energy, shear forces applied with a good dispersion equipment, and a chemical (polar) activator to reach the proper level of delamination of the organo-clay particles.

Polar Activator: Dosage of polar activator (such as 95%ethanol, 95%methanol, 95%acetone or propylene carbonate) is 30%-50% by weight of BS-1C-FF.

It is always recommended to determine the proper level of addition by experiment. Either defect or excess of chemical activator would result in poorer viscosity development.
