Silicon Dioxide (SiO2) Nanopowder/Nanoparticles

Purity: 99+%, Size: 20 nm

Silicon Dioxide (SiO2) Nanopowder is a highly pure, amorphous silica nanomaterial engineered with a finely controlled nanometer-scale particle structure. Characterized by its nearly spherical morphology and bulk density, this advanced powder offers an outstanding specific surface area that drives intense surface activity and high reactivity. The material is meticulously developed to ensure uniform particle dispersion, preventing severe agglomeration within complex solid or liquid matrices. With its balanced chemical neutrality and high physical stability, this premium silica serves as an indispensable functional additive designed to upgrade the mechanical durability, processing rheology, and structural performance of high-end industrial systems.

Technical Properties

Applications

• High-Performance Coatings, Paints & Inks: Utilized as an advanced additive to optimize pigment suspension and prevent sedimentation or phase separation during long-term storage. It significantly improves the scratch resistance, film toughness, and uniform gloss control of industrial coatings and clearcoats without altering their optical transparency or color depth.
• Rheology Control & Thixotropic Systems: Functions as a highly efficient thickening and thixotropic agent in epoxy resins, polyurethanes, adhesives, and sealants. It provides excellent anti-sagging, anti-running, and non-slump characteristics on vertical surfaces during application, while maintaining smooth, uniform flowability under shear stress.
• Plastics, Rubber & Advanced Composites: Applied as a dynamic reinforcing functional filler in engineering plastics, silicone rubbers, and polymer composites. The high specific surface area allows for strong interfacial bonding with organic polymer chains, markedly boosting the tensile strength, tear resistance, and thermal stability of the host structure.
• Advanced Ceramics & Thermal Insulation: Leveraged in the manufacturing of high-tech structural ceramics, refractory materials, and thermal barrier systems. Its optimized packing capability and nearly spherical particles facilitate excellent structural cohesion, enhancing sintering efficiency and promoting uniform physical integrity in the final cured components.
