High purity organic thixotropes bentonite for all oil based drilling fluids DE-181

Organic bentonite clay DE-181 is a kind of organo clay rheological additive. Especially white bentonite clay is recommended to be applied in medium polarity and high polarity system including aromatic and aliphatic solvent.


Composition Organic derivative of a montmorillonite clay

Appearance Fine powder, light yellow

Moisture content (105ºC,2hr) ≤3.5%

Loss on ignition (1000ºC) 35%-37%

Bulk density 0.40~0.60g/cm3

Fineness (<74μm, %) ≥99%

Dispersion fineness (μm) ≤10


    Base oil:

  • Diesel Oils
  • Crude Oils
  • Mineral Oils
  • Synthetic Oil
  • Alpha Olefins
  • Low BTEX base oil

Viscosifying drilling Fluids:

  • Oil based drilling fluids
  • Invert emulsion fluids
  • Workover fluidsl
  • Completion fluids
  • Casing packs
  • Packer fluids
  • Spotting fluids



  • Easy dispersing, fine particle size
  • High purity and low silica content
  • High viscosity and thixotropy
  • Eliminate polar activator in medium and high polarity solvent
  • Wide application range. It can be applied in almost all resins and solvents


DE-181 can be added directly in powder under high shear condition. The addition is recommended to be before grinding procedure to get the best effectiveness. Addition level is commonly 0.2%~1.0%. In low polarity system such as mineral spirit, if polar activator is added, better efficiency can be achieved.

Dosage of polar activator is suggested to be 10%-20% of DE-181 by weight.
