Silicon Dioxide (SiO2) Nanopowder/Nanoparticles

Purity: 95.5+%, Size: 55-75 nm 

Silicon Dioxide (SiO2) Nanopowder is a high-purity, hydrophilic fumed silica engineered to provide exceptional rheological control, liquid thickening, and reinforcement across a vast range of industries. Characterized by its ultra-fine primary particle size and highly branched aggregate architecture, this premium nanomaterial exhibits outstanding thixotropic efficiency and anti-settling performance. It offers remarkable physical stability, optical transparency, and free-flow enhancement when incorporated into complex liquid or powder formulations. Manufactured to meet the most rigorous quality standards, it serves as a benchmark additive for optimizing processing behavior, preventing sagging, and upgrading mechanical durability.

Technical Properties

Applications

• Rheology & Viscosity Control in Resins: Functions as a highly potent thickening and thixotropic agent in epoxy, polyurethane, and unsaturated polyester resins. It effectively prevents sagging, dripping, and running on vertical surfaces during application while ensuring excellent leveling properties and structural homogeneity.
• High-Performance Coatings, Paints & Inks: Widely utilized in automotive, industrial, and decorative coatings to optimize pigment suspension and prevent sedimentation or phase separation during long-term storage. It significantly improves the scratch resistance, film hardness, and uniform finish of coatings without altering their transparency or color depth.
• Adhesives, Sealants & Silicone Rubbers: Acts as a critical reinforcing filler in high-strength structural adhesives, silicone sealants, and elastomers. It substantially boosts cohesive strength, shear resistance, and tear durability while providing optimal extrusion control and non-slump characteristics during manufacturing.
• Powder Conditioning & Free-Flow Enhancement: Applied as a highly efficient anti-caking and fluidizing additive in moisture-sensitive or cohesive powder processing. By coating the host particles, it drastically reduces inter-particle friction and agglomeration, ensuring smooth free-flow behavior during automated feeding, transport, and storage.
