Organically modified bentonite, as a chemical additive, has a wide range of applications. Its main functions can be summarized as follows:
- Application in Cosmetics:
o Enhances the thixotropy and suspension of cosmetic fluids, improving the storage stability of emulsions.
- Application in High-Temperature Greases:
o Acts as a thickening and rheology agent in bentonite greases, providing excellent high-temperature performance with a drop point above 220°C.
o Offers strong thickening capabilities and stability under high temperature and pressure.
- Application in Paint and Ink Production:
o Improves the thixotropy, suspension, and stability of paints and inks.
o Prevents sagging and pitting, increases film thickness.
o Prevents paint sedimentation, extending the fading period and shelf life.
o In inks, it acts as a thickening agent, controlling permeability, and enhancing printability.
- Application in Deep Well Drilling Muds:
o Serves as a thickening, suspending, and stabilizing agent in organic drilling muds, enhancing rheology, salt resistance, and thermal stability.
- Application in Coatings:
o Functions as an anti-settling and thickening agent in metal anti-corrosion coatings, providing resistance to corrosion, abrasion, saltwater erosion, impact, and sagging.
- Other Applications:
o Due to its excellent physical and chemical properties, such as anti-sagging, anti-settling, thickening, rheology, adsorption, and suspension, it is widely used in paints, coatings, inks, greases, oilfield drilling fluids, and cosmetics.

Organically modified bentonite is an important industrial material, primarily serving in the following capacities:
Thickening and Suspension Stability:
o In liquid systems, it forms a network structure that effectively increases the system’s viscosity and keeps solid particles suspended, maintaining system stability.
Thixotropic Properties:
o In a stationary state, it forms a solid-like structure. Under shear forces like stirring or pumping, this structure temporarily breaks down, increasing fluidity. Once the shear force is removed, the structure reforms, a property known as thixotropy. This makes organically modified bentonite widely applicable in coatings, inks, and drilling muds.
Lubrication and Dispersion:
o In the dyeing of textile fibers and fiberglass resins, it acts as a lubricant and dispersant, improving dye uniformity and rate, preventing the separation of fibers and resins, and enhancing processing efficiency.
High-Temperature and Radiation Resistance:
o In specific applications, such as thickening agents in high-temperature greases, it exhibits excellent resistance to high temperatures and radiation, maintaining stability under extreme conditions.
Other Applications:
o Organically modified bentonite is also used in cosmetics, lubricants, and oilfield drilling fluids, showcasing broad application prospects.
In summary, organically modified bentonite plays a vital role in various fields due to its unique physical and chemical properties. It serves as an indispensable rheological additive, performing different functions across diverse industries.

Advantages | What is organophilic clay used for?
- High purity, low silica content.
- Fine dispersion and particle size.
- Good self-activated property.
- Gel is very transparent and of light color
- High Thixotropy.
- Cost effective.
Application
CP-21A is used in the following applications:
- Lubricating grease, mainly in grease based on mineral oil.
- Paints including decorative paint, industrial paint.
- Sealants and adhesive.
Using
It is a super dispersible grade that can increase flexibility in paint manufacturing. It can be added directly in powder under high shear condition. Addition level is commonly 0.1%~1.0% (7%-10% in greases) of total formulation by weight. Polar activator can be eliminated, but small dosage of polar activator is helpful to achieve better performance.
When non-aliphatic solvent presents, the effectiveness of CP-21A should be evaluated.
