General description

Trichloro(1H,1H,2H,2H-perfluorooctyl)silane (PFOCTS) is a chlorosilane that forms a self-assembled monolayer (SAM) on a variety of substrates. It is majorly used to modify the surface with superhydrophobic properties. It is a biocompatible polymer with low surface energy. PFOCTS exhibits anti-fouling properties with high wettability which facilitates the release of different composites from the mold.[1][2]

Application

PFOCTS is a coupling agent that is used to silanize the substrate for the fabrication of microfluidic devices using soft lithography.[3][4] It can also be used on silicon base that forms a chemically patterned surface for quantitative analysis of insoluble surfactants in the polymeric matrix.[5] Alumina membranes can be treated with PFOCTS for the formation of surperhydrophobic polyimide (PI) based nanotube arrays.[6]

Questions

1–2 of 2 Questions  

  1. 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

  2. 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
