pH variety: 8.5– 10.5 (alkaline, stabilized with sodium or potassium ions).
Fragment size: 5– 100 nm (depending upon grade).
Thickness: Roughly 1.1– 1.3 g/cm ³ at 25 ° C.Viscosity: Low, comparable to water.
Applications
This nano silica diffusion functions well in layers, adhesives, and sealers to improve firmness, scrape resistance, and toughness. It improves the mechanical stamina of cementitious products and is made use of in high-performance concrete. In polishing slurries, it supplies uniform surface finishes for glass and semiconductors. The item also serves as a rheology modifier and anti-settling agent in paints and inks. Its little particle size allows deep infiltration right into permeable substrates, making it beneficial for stone and stonework combination.

Applications of Nano Silicon Dioxide SiO2 Dispersions (CAS No. 7631-86-9)
Coatings and Paints
Nano silica dispersions improve scratch resistance and toughness in coverings. They develop a thick, protective layer on surface areas. This makes paints last much longer and look far better gradually. The fragments also help control gloss levels without affecting shade.
Adhesives and Sealants
Adding colloidal nano silica enhances strength and security in adhesives. It stops sagging during application and boosts bonding efficiency. The product stays versatile while standing up to wetness and warm.
Polishing and Accuracy Finishing
These diffusions are made use of in high-precision polishing slurries for glass, silicon wafers, and optical elements. The uniform bit size enables smooth, also elimination of surface layers. This results in fewer defects and higher quality.
Concrete and Building And Construction Products
In cement-based products, nano SiO2 fills up small spaces in between bits. This leads to more powerful, denser concrete with lower permeability. Structures end up being much more resistant to water, chemicals, and weathering.
Electronic devices and Encapsulation
Colloidal silica helps safeguard sensitive digital parts. It is made use of in encapsulants and underfill products to take care of thermal stress and anxiety. The diffusion additionally sustains much better insulation and long-term dependability.
Catalyst Supports and Purification
Thanks to its large area and steady framework, nano silica works well as an assistance for catalysts. It likewise enhances purification membrane layers by boosting circulation rates and capturing fine bits properly.
Personal Treatment and Cosmetics
In lotions, sun blocks, and make-up, nano silica regulates oil, includes structure, and improves spreadability. It remains gentle on skin while offering products a smooth feel.
All these uses rely on the very same core features: small fragment dimension, high pureness, and stable diffusion in water or various other providers. The CAS number 7631-86-9 determines this certain kind of silicon dioxide used across markets.

5 FAQs of Nano Silicon Dioxide SiO2 Dispersions CAS No.7631-86-9 Colloidal Nano Silica
Frequently Asked Questions About Nano Silicon Dioxide (SiO₂) Dispersions
What is Nano Silicon Dioxide SiO₂ Dispersion?
Nano Silicon Dioxide SiO₂ dispersion is a stable liquid that contains tiny silica particles evenly spread in water or another solvent. These particles are extremely small—usually between 5 and 100 nanometers. The product carries CAS No. 7631-86-9 and is also known as colloidal nano silica. It appears clear or slightly cloudy and stays mixed without settling quickly.
What are the main uses of this material?
This dispersion is used in many industries. It strengthens coatings, improves scratch resistance, and adds durability to paints and varnishes. In electronics, it helps make better insulating layers. It is also added to adhesives, sealants, and composites to boost performance. Some personal care products use it for texture control and stability.
Is it safe to handle?
Yes, but you must follow basic safety steps. Wear gloves and eye protection when handling it. Avoid breathing mist or vapor. Store it in a cool, dry place away from strong acids or bases. Always check the Safety Data Sheet (SDS) before use. The product is not classified as highly hazardous, but good practice reduces any risk.
How should it be stored?
Keep the container tightly closed. Store it at room temperature, ideally between 5°C and 30°C. Do not freeze it. Freezing may damage the dispersion and cause the particles to clump. Use clean tools to avoid contamination. Once opened, use it within the time frame listed on the label.
Can it be mixed with other materials?
Yes, it mixes well with water-based systems. It works in many resins, polymers, and coatings. However, always test a small batch first. Mixing with high-salt solutions or extreme pH liquids may cause it to gel or separate. Stir gently to keep the particles evenly distributed.
