Highly pure, hydrophilic fumed silica with controlled particle size distribution for consistent rheology control.
Optimized surface area (~200 m²/g) for efficient thickening and anti-settling performance in liquid systems.
Low dust generation during handling due to proprietary surface treatment and gentle agglomeration structure.
Excellent dispersibility in polar solvents and resins without requiring high-shear pre-dispersion.
Stable performance across a wide temperature range, supporting processing flexibility in industrial formulations.
Thixotropic agent in silicone sealants and RTV adhesives.
Rheology modifier in high-performance coatings and architectural paints.
Anti-settling additive in pigment concentrates and inkjet inks.
Reinforcing filler in specialty elastomers and liquid silicone rubber (LSR) compounds.
Free-flow aid and anti-caking agent in pharmaceutical and food-grade powders.
