General description

Transparent titania (TiO2) paste is a visual range transparent paste that has a large surface area to volume ratio. The average diameter of the TiO2 nanoparticle within the paste is 20nm and the transparent sintered films are around 6-7 μm thick per printed layer.

Application

Use Transparent Titania Paste in applications that require a transparent sintered titania film with a large surface/volume ratio.

Transparent Titania Paste is formulated to yield sintered film thicknesses of 6-7μm when screen printed with a 43T mesh. Transparent Titania Paste has highly dispersed and stable anatase nanoparticles.

It is optimised for screen printing using a synthetic 43T mesh screen (or similar). After drying; this paste must be fired at or above 500°C. This results in a transparent sintered layer; with a film thickness of approximately 6-7μm for one printed layer and ~12μm for two printed layers; when using a 43T mesh screen.

The paste exhibits optimal rheological properties that provide good surface uniformity and contains organic binders specially formulated to provide versatile porosity suitable for a range of dye/electrolyte systems.

Storage: Store in the dark at 20°C
TiO2 paste forms a screen printed film which is majorly used as a conduction band on indium tin oxide (ITO) or fluorine doped tin oxide (FTO) based substrates for dye sensitized solar cells and for major photovoltaic based applications.
