A leading organoclay company prioritizes formulating products that enhance coating performance by utilizing bentonite’s structural advantages.
These companies engineer organoclays where the distinctive three – dimensional structure wraps water, pigments, and fillers, achieving effective thickening and superior storage stability for coating systems.
During application, when shear force is applied, the organoclay’s network breaks down, showing shear – thinning to improve leveling, and reforms via hydrogen bonding once shear stops, offering strong anti – sagging effects.
In static storage, the organoclay from such a company features particles dispersed among microparticles for support; under shear, these particles realign along the flow direction and quickly rearrange when shear ceases. This expertise makes the organoclay company a trusted provider of products that enhance coating storage stability and thixotropy.
Organoclay is the commercially available organically modified clay mineral used as a rheology modifier and anti-settling additive in oil-based systems including drilling fluids, solvent-based coatings, and lubricating greases; full product specifications are at organoclay — product specifications and application guide. The organophilic clay surface chemistry, dispersion method, and compatibility with different base oils and solvents are explained in organophilic clay — surface chemistry and industrial applications. To source organoclay directly from a China manufacturer, see organoclay supplier — factory-direct supply and technical support.
The CP series of organic bentonite is mainly used in solvent-based and water-based paints, coatings, inks, lubricants, cosmetics, and oilfield drilling fluids.
Rheology modifiers are an organo clay (modified bentonite), designed especially for use in solvent based system. Organic Clay can be used widely in solvents from low polarity to medium-high polarity.

Application of Organo clay
Organo clay is used in the following applications:
- Marine paint, Industrial paint, heavy-duty, anticorrosion paint such as bituminous coatings, epoxy paints, chlorinated rubber paints
- Grease
- Inks
Sealant
Using
Organo Bentonite disperses under high shear and requires a polar activator 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 45%~60% of CP-40 in weight. If in xylene system, addition level of polar activator is about 30%-40% of CP-40 in weight.
Pre-gel is made as below procedure.
- Charge solvent to mill
- Slowly add CP-40 (6-10% by weight of total pre-gel) to mill under agitation.
- Mix at high speed for 5 minutes.
- Add polar activator.
- Mix at high speed for 5 minutes.
