Its hydroxyl-rich surface chemistry enhances interaction with moisture and formulation components, making it ideal for advanced research in electronics encapsulation, rubber composites, coatings, adhesives, and optoelectronic materials. Supplied in a 100 g bottle, this research-grade powder empowers precise control over dispersion, rheology, and optical properties for next-level material development. ## Description XFNANO XFI03 is an amorphous silicon dioxide nanopowder developed for laboratory, university and industrial materials research. It is supplied as a fine white powder with 99% purity, a particle size of 20 nm, a specific surface area of 145–160 m²/g and a net weight of 100 g. The particle surface contains silanol groups that can interact with water molecules and other formulation components. Because the material has a strong affinity for moisture, it should be handled promptly and kept sealed when not in use. Potential research areas include epoxy encapsulation systems, rubber composites, coatings, adhesives, rheology modification and silica-containing optical or electronic material formulations. Final dispersion, mechanical, rheological, dielectric, thermal and optical performance depends on loading, matrix chemistry, processing conditions and test method. Review the product-specific SDS and technical information before use. For laboratory and industrial R&D use only. ## Features - 20 NM SILICA NANOPOWDER – White amorphous silicon dioxide powder with 99% purity, 20 nm particle size and 100 g net weight. - 145–160 M²/G SURFACE AREA – High specific surface area provides an extensive particle interface for laboratory formulation and material-development studies. - HYDROXYL-RICH SURFACE – Surface silanol groups can interact with moisture and formulation components; keep the powder sealed and control humidity during handling. - MULTIPLE MATERIAL SYSTEMS – Suitable for evaluation in electronic encapsulation compounds, rubber composites, coatings, adhesives and optoelectronic materials. - FORMULATION-DEPENDENT PERFORMANCE – Dispersion, rheology, reinforcement and optical behavior depend on loading, matrix, mixing method, processing and test conditions. ## Technical Specifications | Specification | Value | |---------------|-------| | % Assay of Chemical(s) | 99 | | ASIN | B08TLXWPPG | | Best Sellers Rank | #241,231 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #688 in Analytical Reagents | | Brand Name | XFNANO | | Container Type | Bottle | | Customer Reviews | 4.7 4.7 out of 5 stars (7) | | Item Form | Powder | | Item Highlight | Hydroxyl-rich amorphous silica for electronic encapsulation, rubber, coatings and materials research | | Item Weight | 100 Grams | | Manufacturer | XFNANO | | Manufacturer Part Number | XFI03-001-1 | | Model Number | XFI03-001-1 | ## Product Details - **Brand:** XFNANO - **Item Form:** Powder - **Item Weight:** 100 Grams - **Package Information:** Bottle - **Percentage assay:** 99 ## Images ![Silicon Dioxide SiO2 Nanopowder, 99%, 20 nm, 100 g Research Grade - Image 1](https://m.media-amazon.com/images/I/31xwbGwT3IL.jpg) ![Silicon Dioxide SiO2 Nanopowder, 99%, 20 nm, 100 g Research Grade - Image 2](https://m.media-amazon.com/images/I/515AFnGEBaL.jpg) ![Silicon Dioxide SiO2 Nanopowder, 99%, 20 nm, 100 g Research Grade - Image 3](https://m.media-amazon.com/images/I/51m3xuaeJHL.jpg) ![Silicon Dioxide SiO2 Nanopowder, 99%, 20 nm, 100 g Research Grade - Image 4](https://m.media-amazon.com/images/I/51ftYsnDwhL.jpg) ![Silicon Dioxide SiO2 Nanopowder, 99%, 20 nm, 100 g Research Grade - Image 5](https://m.media-amazon.com/images/I/51TskRyfiTL.jpg) ## Questions & Answers **Q: Is this product dispersible in water?
