Off white appearance is a notable feature of specific organoclay products, distinguishing them in both visual appeal and functional performance. Among these, one type of off white organoclay is capable of forming thixotropic colloids in suitable solvents.
It does not demand high – speed shear dispersion but necessitates the use of small quantities of alcohol – based activators or other dispersants. Additionally, self – activating organoclay, typically showcasing an off white look, can create uniform dispersions in applicable solvents.
It stands out as it requires neither high – speed shear dispersion nor the addition of alcohol – based activators or other dispersants, making this off white organoclay a versatile choice for various uses.
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.

Organoclay off white appearance
- High gelling efficiency,high viscosity
- Wide application range, it can be applied in all low, middle and high polarity range
- Produce reproducible thixotropic consistency over a wide temperature range
- Imparts particle suspension, preventing hard settling of pigment and fillers
- Exerts strong film reinforcing action in organic binder systems
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.
- Organoclay off white appearance
