High purity organophilic clay,organoclay with good expending ratio for all oil based drilling fluids CP-180B

Organoclay OBM Viscosifier

High purity organophilic clay , organoclay with good expending ratio for all oil based drilling fluids CP-180B

Organophilic bentonite can be dispersed with a small amount of polar activator at high speed shear. Organic bentonite clay is applicable in sealants, high temperature lubricating greases, bitumen paints, chlorinated rubber paints, high-grade paints, furniture paints, etc.Organic modified bentonite clay can be added at any step. Then polar activator dosage is 20% of organoclay with dispersion at high speed or by mill. Usually, the dosage in paints is 0.2-1.5%, while in high thixotropic or thick paints is 1-2.7%.

High Purity Organophilic Clay Expending Ratio Oil Based Drilling Fluids



Chemical ingredient Alkyl Quaternary Ammonium bentonite Quartz(SiO2)
CAS. No. 68953-58-2 14808-60-7


Rheological additive CP-180B is a new style organoclay with easily dispersing, super thixotropic effect, good transparency. Applicable to low and middle polar solvent systems, Organoclay bentonite has good anti-sagging, anti-flowing , ideal thickening and thixotropic property. Organoclay rheological additive is an improved grade of CP-180. It is more fine, and easier to be dispersed compared with CP-180.

1, Properties

Composition Organic derivative of a montmorillonite clay

Appearance Fine powder,               light yellow

Moisture content (105℃,2hr)         ≤3.5%

Loss on ignition (1000℃)               29%-32%

Bulk density                                   0.53g/cm3

Fineness (<74μm, %)                    ≥98%

2, Advantages

  • Exerts gelling efficiency over a wide range of intermediate and low polarity
  • Easy dispersing
  • The gel is colourless and of high clarity
  • Produce reproducible thixotropic consistency over a wide temperature range
  • Imparts particle suspension, sag resistance without impairing flow and leveling, preventing hard settling of pigment and filler
  • Exerts strong film reinforcing action in organic binder systems

3, Application

CP-180B is used in the following applications:

  • Transparent coatings
  • Nano-composite
  • Lubricant Grease, ink, sealant
  • Replacement of fumed silica
  • Cosmetic
  • OIl drilling mud

4, Using

CP-180B disperses under high shear and requires a polar activator (30%~40%) for best efficiency. Heat is not required to obtain good dispersion. Addition levels are typically in 0.2%~2.0%. Polar activator (95% Ethanol or 95% Methanol) is needed. Normally addition level of polar activator is recommended to be 30%~40% of CP-180B in weight.

5, Safety
