ASTRA REO®
Rheology Modifiers
Rheology additives for precise viscosity tuning in solvent-borne, waterborne, and solvent-free systems. Prevent sedimentation, separation, ensure controlled flow and sag resistance.
Why do we use rheology modifiers?
Rheology modifiers fine-tune the viscosity profile of coatings, inks and adhesives. They prevent sedimentation, separation and sagging while ensuring controlled flow during application. The right rheology enables thicker, more uniform films that resist running on vertical surfaces.
Key Benefits
- Sag Resistance — prevents drips on vertical surfaces
- Anti-Settling — keeps pigments and fillers suspended
- Thixotropic Behavior — flow when applied, set when at rest
- Wide pH Tolerance — works in alkaline and acidic systems
- Compatible with Solvent, Water, UV systems
- Improved Storage Stability
Impact on Coating Performance
Proper rheology control transforms formulations into reliable, easy-to-apply products. ASTRA REO additives reduce waste, improve application speed and produce consistent film thickness across complex geometries.
O – organosoluble, WB – water-based, UV – radiation-curable
