Thixotropic Gel Additive: The Ultimate Guide to Organoclay Applications
What is Thixotropic Gel Additive?
A thixotropic gel additive, commonly known as organoclay or rheology modifier, is a specialized material that exhibits unique flow properties. When at rest, it maintains a gel-like structure, but under applied stress or shear, it becomes fluid and flows easily. This reversible behavior makes it invaluable across numerous industrial applications.
Key Characteristics
- Reversible gel-to-fluid transition under shear
- Excellent thickening and suspending properties
- Anti-settling and anti-sagging capabilities
- High temperature stability
Understanding Organoclay Technology
Molecular Structure
Organoclay is derived from natural montmorillonite clay through organic modification, creating a material with enhanced compatibility in organic solvents and improved rheological properties.
Thixotropic Behavior
The unique three-dimensional network structure of organoclay provides excellent thixotropic properties, allowing materials to flow when agitated and gel when at rest.

Usage Guidelines and Best Practices
General Application Procedure
- Heat base oil to 60-70°C if conditions permit
- Add organoclay while stirring (7-10% of total formulation)
- Stir for 5-10 minutes to ensure proper dispersion
- Add polar activator if required (2-3% of total formulation)
- Continue stirring for 25-30 minutes
- Process through colloid mill and homogenizer
- Deair, filter, and package
Important Notes
- Use high-speed dispersant for better results
- Polar activator: acetone/water (95/5)
- Activator dosage: 20-30% of organoclay weight
- High shear promotes better dispersion
Storage Requirements
- Store in dry, well-ventilated area
- Temperature range: 0°C-30°C
- Keep container tightly closed
- Quality guarantee: 24 months
