High specific surface area (approx. 200 m²/g) for superior reinforcement and thickening efficiency.
Hydrophilic surface chemistry enabling easy dispersion in polar systems such as water, alcohols, and glycols.
Consistent particle morphology and narrow primary particle size distribution (7–12 nm) ensuring reproducible performance.
Low residual sodium content (<0.05 wt%) supporting high purity requirements in sensitive applications like electronics and pharmaceuticals.
Excellent flowability and low dust generation during handling due to optimized agglomerate structure.
Thickener and rheology modifier in water-based paints and coatings.
Anti-settling agent in pigment dispersions and aqueous ink formulations.
Reinforcing filler in silicone elastomers requiring high transparency and mechanical stability.
Free-flow aid in food-grade and pharmaceutical powders (compliant with FDA 21 CFR §172.430).
Viscosity stabilizer in adhesives and sealants based on acrylic, polyurethane, or epoxy resins.
