Organically modified bentonite | viscosifiers organoclays   

Organically modified bentonite CP-169 is an viscosifiers organoclays.(modified montmorillonite), designed especially for use in solvent based system including intermediate and low polarity range organic liquid..  


Composition                      Organic derivative of a montmorillonite clay

Appearance                       Fine powder, white

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

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

Bulk density                       0.53g/cm3

Fineness (<74μm, %)               ≥98%


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 fillers 

Exerts strong film reinforcing action in organic binder systems


Rheology organoclay CP-169 is used in the following applications:

Paints & coatings with solvent of low to medium polarity

Lubricant Grease, ink, sealant


Oil drilling mud


Organo bentonite CP-169 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-169 in weight

Kraft bag or kraft complex interior with PE or customized


Organoclay Bentonite CP-169 has a shelf life of 2 years, and should be stored in ventilated cool and dry place.
