Organophilic Bentonite High-Performance Rheology Modifier
Advanced organoclay rheology modifier derived from sodium bentonite powder. Delivers exceptional thickening, thixotropic properties, and anti-settling performance across solvent-based systems and oil-based formulations.
What is Organophilic Bentonite?
Organophilic bentonite, also known as organoclay or modified montmorillonite, is a high-efficiency rheology modifier created through the modification of sodium bentonite powder with organic compounds.
This specialized clay mineral is specifically engineered for solvent-based systems, offering superior performance in low-polarity to high-polarity solvents. When incorporated into formulations, it provides exceptional thickening ability, thixotropic properties, and anti-settling characteristics.
Our organophilic bentonite serves multiple functions as a rheological additive, suspending agent, anti-sagging agent, thixotropic agent, and viscosity control agent across diverse industrial applications.
