Dry processed organophilic bentonite clay
The production and processing methods of organophilic clay bentonite are divided into dry processed and wet processed. The organic bentonite processed by the method is mainly suitable for coating, ink, lubricating grease, and water treatment and oil-based drilling fluids.

Dry processed organophilic bentonite clay
What it is?
Modified bentonite clay: A natural clay (primarily montmorillonite) that has been chemically altered to be hydrophobic (water-repelling) and organophilic (The ability to adsorb oil is particularly outstanding. ).
Dry processing bentonite: The production process involves drying the bentonite thoroughly and then applying the organic modifier, which is a key step for its performance in organic solvents and oils. (It is particularly suitable for the production of oil drilling fluid based on diesel systems, mineral oils, and synthetic oils.
What it’s used for？
- Oilfield drilling fluids: To suspend weighting materials and other solids, especially in oil-based muds, All oil based drilling fluids, Invert emulsion fluids, Workover fluids,Fracture fluids
- Paints and coatings: As an anti-settling agent.It is used in water-based and solvent based paint coatings.
- Inks: As a thixotropic (gel-like) agent for viscosity control.In printing ink, its rheological properties are extremely outstanding.
- Greases and lubricants: As a gelling and thickening agent.In the production of lubricating grease, it is used as an excellent rheological additive, anti settling agent, and accelerator.
- Other applications: Used in areas where a solid needs to be suspended in an organic liquid. It can also be applied to cosmetic adhesives and sealant. Then in the industrial sector.
How It’s Made？
Raw Material Selection: High-purity bentonite is carefully selected to ensure stable performance.
Washing & Pre-Treatment: The clay undergoes thorough washing to remove natural impurities and prepare it for modification.
Ion Exchange Process: The purified clay is reacted with an organic modifier—typically a quaternary ammonium compound—to replace its natural cations and transform it into an organophilic material.
Washing & Drying: After modification, the material is washed again and fully dried to stabilize its properties.
Crushing & Grading: The dried product is milled and accurately graded to meet the particle size requirements of various applications.
Comprehensive Inspection & Sample Retention: Each batch is rigorously tested, with representative samples kept for quality tracking and future reference.
Packaging: The finished organoclay is securely packaged to ensure product integrity during storage and transportation.
