Highly pure, hydrophilic fumed silica with controlled surface chemistry for consistent performance.
Optimized particle size distribution for superior thickening and rheology control in liquid systems.
Excellent dispersibility in polar and non-polar media without requiring high-shear processing.
Low abrasivity and high thermal stability, supporting use in sensitive formulations and elevated temperature processes.
Batch-to-batch reproducibility ensured through stringent manufacturing controls and ISO-certified production.
Thixotropic additives in silicone sealants and RTV adhesives.
Rheology modifiers in coatings, inks, and UV-curable formulations.
Anti-settling agents in pigmented paints and automotive refinish systems.
Free-flow aids and reinforcing fillers in powder coatings and thermoset resins.
Stabilizers in pharmaceutical suspensions and personal care gels.
