Silicon Dioxide (SiO2) Nanopowder/Nanoparticles

Purity: 99.5+%, Size: 15-35 nm 

Silicon Dioxide (SiO2) Nanopowder is a synthetic, amorphous fumed silica engineered for advanced surface modification and rheological control. Characterized by its ultra-fine particle size and highly branched aggregate structure, this premium nanomaterial exhibits exceptional thixotropic efficiency and anti-settling performance in liquid systems. It provides outstanding reinforcement capabilities, optical transparency, and free-flow properties across a broad spectrum of matrices. Manufactured to ensure strict consistency, this versatile silica powder is a crucial additive for optimizing mechanical stability, preventing sagging, and adjusting viscosity in high-performance industrial formulations.

Technical Properties

Applications

• Rheology Control & Thixotropy in Resins: Widely utilized as a powerful thickening and thixotropic agent in epoxy, polyurethane, and unsaturated polyester resins. It prevents sagging and dripping on vertical surfaces during application while maintaining excellent leveling properties and structural stability.
• Coatings, Paints & Printing Inks: Integrated into high-end automotive coatings, industrial paints, and printing inks to optimize pigment suspension and prevent sedimentation during storage. It enhances the scratch resistance, film hardness, and uniform gloss control of the final cured surface without compromising optical clarity.
• Adhesives & Sealants Formulation: Functions as a critical reinforcing filler in industrial adhesives, structural sealants, and silicone rubbers. It significantly boosts the cohesive strength, shear resistance, and mechanical durability of the joints while controlling the extrusion behavior during processing.
• Free-Flow & Anti-Caking Additive: Applied in powder processing and compounding industries to improve the flowability and storage stability of moisture-sensitive or sticky powders. By coating the host particles, it effectively prevents caking, bridging, and agglomeration during transport and automated feeding.
