Organoclay Bentonite CP-180B

Organoclay Bentonite CP-180B is an organo clay (modified montmorillonite), designed especially for use in solvent based system including intermediate and low polarity polarity range organic liquid. Organoclay is an improved grade of CP-180. Organoclay rheological additive is more fine, and easier to be dispersed compared with Solvent based Organoclay CP-180.  


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%


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


Organoclay Viscosifiers CP-180B is used in the following applications:

Transparent coatings

Lubricant Grease, ink, sealant 



 Replacement of fumed silica 


Organo bentonite 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 Rheology organoclay CP-180B in weight.
