Description générale

Diurethane dimethacrylate (DUDA) is a mixture of isomers that belongs to the class of methacrylate monomers. It is a bifunctional monomer, which contains two methacrylate groups and two urethane linkages. It is commonly used in the field of polymer chemistry as a crosslinking agent or a reactive diluent in adhesive materials, coatings, and composites. It has good mechanical and adhesive properties, which makes it suitable for various polymer applications.

Application

The Progress in Development of Dental Restorative Materials
Diurethane dimethacrylate can be used as:
  • A monomer in the synthesis of the shape memory polymer that is used as the matrix material for the preparation of high-strength and stiffness composites. These composites show excellent shape memory behavior and mechanical strength, making them suitable for bone fixation devices.
  • A crosslinking agent to prepare the denture biomaterials, which contain antifungal drugs incorporated into the polymer matrix for controlling drug delivery.
  • A crosslinking agent in the synthesis of anion exchange membranes (AEMs) for use in electrochemical devices.
Diurethane dimethacrylate has been used as a precursor to fabricate the multifunctional polymer nanocomposite with enhanced luminescence activity. It can also be used in digital light processing (DLP) mediated 3D printing.

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.
