Descrição geral

Methoxytrimethylsilane (MTMS) is a silylating agent, which is majorly used to provide a hydrophobic surface coating with a high water contact angle and low surface energy.[1][2]

Aplicação

Effect of chemical modification of diglycidyl bisphenol A based epoxy resin with methyltrimethoxy silane (MTMS) was studied. 1 It was used to quench lab ware with MTMS while handling HF/pyridine.{90}
Superhydrophobic recycled polyethylene terephthalate (rPET) aerogels can be fabricated by using rPET fibers and polyvinyl alcohol (PVA) and can be coated on MTMS.[3] MTMS on diglycidyl bisphenol A resin (epoxy resin) also shows weathering resistance on exposure to UV by lowering the effect of color change by 45%.[4]

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.

  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
