Physical Properties

Name Solvent pH Viscosity(cP) Ti content(%) Curing(℃) Grain size(nm)
ATNLS-1 Water 7.5~9.0 1.5~3.5 0.9~1.1 RT~60 10~15



  • ATNLS-1 is developed particularly for Window Glass Application; About 5nm ultra fine particles of TiO2 were synthesized in the water, therefore it is not necessary to dilute or any preparation; Directly ready-to Go sol.

Because ATNLS-1 is considered as an ambient temperature drying material, it can be effective around 20 to 50℃;


This may apply curing for faster dryness for hardening, but not necessarily baked with high temperature;

It forms thin film with just a simple spray application; but also the Roller application can be recommended because this is adjusted to maintain transparency of the glass with photocatalytic hydrophilicity.

Caution for Use

At the higher atmosphere temperature in summer, it is suggested not to apply while the surface temperature is too high: Because the evaporation urges the liquid dryness too quickly, which interrupts the liquid to level the film.

Dilution is not recommended but only for quick dryness urged case, it may useful to add alcohol at very small content.

Diluted sol must be used as quick as possible to avoid the viscosity rise, and the agglomeration: diluted sol duration must be a few days after dilution.

Dilution ratio and protocol are instructed at the purchase with a document.

Before start application, it is recommended to apply as a test at somewhere not noticeable.

It is requested to read and prepare with Materials Safety Data Sheet and Product specification which shall be handed at a purchase.
