organo clay rheological additive CP-EZ

Organo clay rheological additive CP-EZ is a kind of organo clay rheological additive.Especially it 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 (105℃,2hr)         ≤3.5%

Loss on ignition (1000℃)            35%-37%

Bulk density                       0.40~0.60g/cm3

Fineness (<74μm, %)               ≥99%

Dispersion fineness (μm)            ≤10


  • 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


CP-EZ is used in the following applications:

  • Paints including decorative paint, industrial paint
  • Grease
  • Inks
  • Oil drilling mud
  • Cleaning agent
  • Oil putty


CP-EZ 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 CP-EZ by weigh
