Features Of Evonik Sipernat D17 Silica

Highly dispersed fumed silica with exceptional surface area (≈300 m²/g) for efficient reinforcement and thickening.
Hydrophilic surface chemistry enabling easy wetting and uniform dispersion in polar systems including water, glycols, and alcohols.
Low bulk density and excellent flowability, facilitating handling and metering in industrial powder processing.
Consistent particle morphology and narrow aggregate size distribution ensure reproducible rheological performance.
Free-flowing, non-agglomerated powder form with low dust generation during handling.

Typical Applications Of Evonik Sipernat D17 Silica

Thickening and anti-settling agent in water-based paints and coatings.
Rheology modifier in adhesives and sealants, especially silicone and acrylic formulations.
Free-flow aid and anticaking agent in food-grade and pharmaceutical powders.
Reinforcing filler in high-transparency silicone elastomers and RTV compounds.
Stabilizer in aqueous agrochemical suspensions and pesticide concentrates.
