High specific surface area (~170 m²/g) for superior reinforcement and thickening efficiency.
Hydrophilic surface chemistry enabling excellent dispersibility in polar systems including water, alcohols, and glycols.
Consistent particle morphology and narrow primary particle size distribution (approx. 12 nm) ensuring reproducible rheology control.
Low residual catalyst content meeting stringent purity requirements for pharmaceutical and food-contact applications.
Free-flowing, low-dusting powder form optimized for safe and efficient handling in industrial processes.
Thickening and anti-settling agent in water-based paints and architectural coatings.
Rheology modifier in high-performance adhesives and sealants, especially silicone and polyurethane formulations.
Free-flow aid and anticaking agent in powdered food supplements and pharmaceutical excipients.
Reinforcing filler in liquid silicone rubber (LSR) and RTV silicone systems requiring clarity and low viscosity.
Stabilizer in agrochemical suspensions and pesticide concentrates to prevent sedimentation and phase separation.
