OC Rheological Additive Technology
Premium organoclay rheological additives engineered for superior viscosity control, thixotropic properties, and anti-sagging performance across diverse industrial applications.
What is OC Rheological Additive? Advanced Organoclay Technology
OC rheological additives are modified organoclays that provide exceptional thickening, suspension, and anti-sagging properties in organic solvent systems. These additives create thixotropic behavior, allowing formulations to flow easily during application while maintaining stability at rest.
Key Benefits
Superior Thixotropy
Creates ideal flow properties - high viscosity at rest, low viscosity under shear for optimal application characteristics.
Anti-Sagging Properties
Prevents settling and sagging in vertical applications, ensuring uniform coating thickness and appearance.
Temperature Stability
Maintains rheological properties across wide temperature ranges, suitable for demanding industrial conditions.
Chemical Compatibility
Excellent compatibility with various organic solvents and resin systems for versatile formulation options.
