Modified Organophilic Clay The Ultimate Rheology Modifier
Discover the revolutionary properties of organophilic clay - a high-performance rheology modifier that transforms industrial formulations across multiple sectors with superior thickening, thixotropic, and anti-settling capabilities.
What is Modified Organophilic Clay?
Modified organophilic clay, also known as organoclay or organobentonite, represents a sophisticated advancement in clay technology. This high-efficiency rheology modifier is created through the chemical modification of sodium bentonite powder, transforming its natural properties to achieve exceptional performance in oil-based and solvent-based systems.
The modification process involves treating montmorillonite clay with organic compounds, creating a material that exhibits remarkable compatibility with non-polar to high-polar solvents. This transformation enables the clay to function as an effective thickening agent, anti-settling agent, and viscosity control agent across diverse industrial applications.

Usage Guidelines & Best Practices
General Application Guidelines
Dosage Levels
Typical addition levels range from 2-10% of total formulation weight, depending on application and desired rheological properties.
Dispersion Method
Add organoclay gradually while stirring to ensure proper dispersion. High-shear mixing improves gel formation and performance.
Temperature Considerations
Heating base materials to 60-70°C can improve dispersion efficiency and reduce processing time.
Post-Correction Capability
Rheological properties can be adjusted after initial mixing, allowing for formulation optimization.
Grease Application Procedure
Required Materials
- • Organoclay: 7-10% of total formulation
- • Polar activator: Acetone/water (95/5)
- • Activator dosage: 20-30% of organoclay weight
Heat base oil to 60-70°C if possible
Add organoclay while stirring, mix for 5-10 minutes
Add polar activator (2-3% of total formulation)
Add other additives, stir for 25-30 minutes
Process through colloid grinding and homogenizer
Deair, filtrate, and package
