01Overview
Crystal-stable 5–10nm anatase titanium dioxide dispersion engineered for 1:4 dilution and industrial coating integration.
Manufacturing a stable, non-settling 5–10nm anatase TiO₂ aqueous sol requires specialized hydrothermal peptization and transition-metal/non-metal doping reactors. Buying cheap TiO₂ powder and mixing it with water results in milky, >200nm agglomerates that settle at the bottom of the bottle and leave chalky white stains on walls. botouseneco 5X Visible-Light Nano-TiO2 Sol Concentrate provides overseas formulators with our factory-synthesized 5X Nano-TiO₂ Sol Concentrate: translucent with a signature sky-blue Tyndall opalescence, neutral pH 6.8–7.5, and ready for 1:4 dilution with pure RO water.
Translucent liquid with characteristic blue Tyndall light-scattering—never chalky or milky like milled powder slurries.
1:4 dilution turns a single 20L export drum into 100 liters of ready-to-spray visible-light photocatalyst.
Non-corrosive neutral sol bonds directly to paint, glass, ceramic, and non-woven filter fibers.
Zero hard caking or phase separation during long-distance sea transport and warehouse storage.
Reaction mechanism
High Zeta-potential surface charge stabilization keeps primary 5–10nm anatase crystallites permanently suspended in neutral aqueous medium without organic dispersing resins. Upon 1:4 dilution with deionized water (<20 µS/cm), the sol forms a 1.0% ready-to-spray photocatalytic coating with strong inorganic self-adhesion.

03Application
Always use deionized water (<20 µS/cm) to preserve nano-colloid Zeta potential.
Hard tap water contains calcium and magnesium ions (Ca²⁺/Mg²⁺) that compress the electrical double layer of 5–10nm nanoparticles and cause flocculation. Always dilute 5X Visible-Light Nano-TiO2 Sol Concentrate at a 1:4 ratio using pure deionized or distilled water.
Record initial HCHO/TVOC readings (mg/m³), room temperature (°C), relative humidity (% RH), and closure window (1h vs. 12h).
Identify whether off-gassing stems from urea-formaldehyde MDF/particleboard, phenolic plywood, solvent lacquers, or textile backings.
Calculate total surface area (m²) of panels, walls, and ceilings to determine exact liquid volume (ml/m²) and nozzle gauge (0.5mm–1.0mm).
Confirm sample evaluation batch, TDS/MSDS export documentation, and commercial drum sizing (1L / 5L / 20L / 25L / 200L).
Must be diluted with low-ion deionized/distilled water; do not mix with hard tap water

08Questions
True 5–10nm nano-TiO₂ sols are stabilized by electrostatic Zeta potential. Divalent ions (Ca²⁺, Mg²⁺) in untreated tap water neutralize surface charges and cause nanoparticles to clump. Using standard deionized or RO water (<20 µS/cm) preserves 100% optical clarity and stability.
