 Rheology Modifiers Coatings | Organic Bentonite Clay

Rheology Modifiers Coatings | Organic Bentonite Clay is a coating additive. As a thickener agent in coatings, Rheology Modifiers also is a Thixotropic agent and dispersant.

Rheology modifiers for waterborne paints and Rheology modifiers for solvent paints are two types of rheology modifiers.

Here we recommend a grade organoclay CP-20 is an conventional organo clay (modified montmorillonite), it is suggested for solvent of low and medium polarity range.

Rheology Modifiers Coatings have fine characteristics of thickening, anti-settling, anti-sag, and storage stability.

  • Exerts fine gelling efficiency.
  • Easy dispersing.Fine particle size 
  • The gel ishigh clarity and of light color.
  • High purity and low silica content.
  • 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.


  • Paints & coatingswith solvent of low to medium polarity, especially for medium and long oil alkyd paint, acrylic
  • Printing ink.
  • Lubricant Grease, ink, sealant.
  • Cosmetic
  • Cleaning agent


Rheology Modifiers In Paints CP-20 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-20 in weight.
