Highly pure, hydrophilic fumed silica with controlled particle size distribution for consistent rheology control.
Optimized surface area (~300 m²/g) to deliver balanced thickening, anti-settling, and thixotropic performance.
Low residual chloride and sodium content, ensuring compatibility in sensitive electronic and pharmaceutical formulations.
Excellent dispersibility in polar solvents and water-based systems without requiring high-shear pre-treatment.
Thermally stable up to 800 °C, supporting high-temperature processing in silicone rubber and coating applications.
Thixotropic agent in high-performance RTV and HTV silicone elastomers.
Rheology modifier in water-based paints, industrial coatings, and architectural emulsion paints.
Anti-settling additive in pigment concentrates and inkjet ink formulations.
Reinforcing filler in specialty adhesives and sealants requiring non-sag properties.
Free-flow aid and binder support in pharmaceutical tablet granulation and nutraceutical powder blends.
