N11 is nano-sized rutile-type titanium dioxide. It is rutile-type titanium white powder produced by the sulfuric acid process. After undergoing inorganic and organic coating treatments, the product has excellent advantages such as good dispersion and fluidity.
It is mainly applied in fields such as fine ceramics, high-end coatings, sunscreen cosmetics, photosensitive materials, and fiber fading reduction.
Good industrial hygiene practices must be applied and dust must be avoided.
This product should not be stored outdoors or exposed to extreme temperatures or moisture. To ensure optimal performance, it is recommended to use the product following the first-in-first-out principle after receiving the goods.

Photocatalysis is both an advantage (self-cleaning, antimicrobial, photodegradation of pollutants) and a risk (may accelerate degradation, yellowing or breakdown of organic matrices). Control methods include: selecting rutile grades or deactivating anatase, applying surface coatings (silica, alumina, silanes) to deactivate catalytic sites, or adding UV stabilizers/antioxidants in the formulation. For evaluation, run accelerated aging tests (UV + heat) comparing treated vs. untreated samples to measure ΔE (color change) and mechanical property changes to decide if passivation is required.
Key test items: particle size distribution (D10/D50/D90), specific surface area (BET), XRD for crystal form ratio, surface charge / zeta potential, surface organic coating content (TGA or elemental analysis), oil absorption / specific gravity, dispersibility (absorbance or particle size stability in the target medium), and heavy metals/volatile residues. Quick acceptance checks: confirm D50 fits your spec, verify the supplier-specified surface treatment is present, run a small dispersion trial in your target medium (no visible agglomeration or rapid settling), and review accelerated photostability data from the supplier.
