Silicon Dioxide (SiO2) Nanopowder from Nanografi (product code NG04SO3103) is a hydrophilic fumed silica with 99.5+% purity and a particle size of 55-75 nm. It is used as an additive to control rheology, thicken liquids and reinforce materials in many industrial formulations.
The powder combines a very fine primary particle size with a highly branched aggregate structure. This gives it strong thixotropic and anti-settling action, so formulations resist sagging and keep solids in suspension. Added to liquid or powder systems, it also contributes physical stability, optical transparency and better powder flow.
The material is amorphous with a spherical morphology, a specific surface area of 175-225 m²/g and a pH of 3.5-4.5 (CAS No 7631-86-9). It is offered in 25gr, 100gr, 500gr and 1000gr packs.
- Thickening and thixotropic agent in epoxy, polyurethane and unsaturated polyester resins to stop sagging and dripping on vertical surfaces.
- Additive in automotive, industrial and decorative coatings, paints and inks to keep pigments suspended and improve scratch resistance and film hardness.
- Reinforcing filler in structural adhesives, silicone sealants and elastomers to raise cohesive strength, shear resistance and tear durability.
- Anti-caking and flow aid for cohesive or moisture-sensitive powders during automated feeding, transport and storage.
