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.[1][2]

Application

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.[1][2][3][4][5][6]
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

Questions

1–2 of 2 Questions  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf
