What is nano silica water dispersion?
Nano silica water dispersion is a stable dispersion of nanometer scale silica particles (typically 1–100 nm) uniformly distributed in water, often with surface modifiers or dispersants to prevent aggregation.
Composition:
Core: silicon dioxide (SiO2) nanoparticles with typical primary particle size <100 nm
Medium: water
Often contains a small amount of stabilizer/dispersant to keep particles from aggregating.
Characteristics of transparent nano SiO2 water dispersion: optical clear, highly uniform particle size, good stability, mature batch production process
Why it matters:
- Improves mechanical strength, abrasion resistance, and hardness when added to coatings, paints, adhesives, concrete, etc.
- Enhances UV resistance, thermal stability, and barrier properties.
- Used in electronics, optics, biomedical carriers, and as a catalyst support.
Typical application fields:
- Chemical mechanical polishing: semiconductor wafer polishing, Metallographic and petrographic grinding and polishing, Optical glass polishing
- Coating: Hardening and wear-resistant coating, Antibacterial coating
- Plastic and rubber modification
- Catalysis and adsorption: Catalyst carrier, Molecular sieve template, Heavy metal adsorption
- Biomedicine: Drug delivery, biological imaging, biological separation, tissue engineering, etc…
