General description

3-[Tris(trimethylsiloxy)silyl]propyl methacrylate (TMSPM) is a silane-modified methacrylate characterized by its unique siloxy functional groups, which impart hydrophobicity and thermal stability. This compound serves as a versatile monomer in polymer synthesis, enabling the formation of siloxane-containing polymers with enhanced mechanical properties. Its excellent adhesion properties make it suitable for use in coatings, adhesives, and sealants.

Application

3-[Tris(trimethylsiloxy)silyl]propyl methacrylate can be used:
  • As a silicone containing monomer to synthesize hydrogels for Opthalmic medical devices such as contact lenses with enhanced mechanical properties. Addition of TMSPM increases the oxygen permeability of the contact lens without affecting light transmission.
  • As a precursor to fabricate dissolved oxygen sensor by embedding a highly stable and highly hydrophobic fluorinated matrix via free radical polymerization.
  • To fabricate bio-based polymers for anti-stain and oil resistant textile coatings. The addition of TMSPM significantly enhances the oil repellence property of the coating.

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
