Opis ogólny

4,4′-Methylenebis(N,N-diglycidylaniline) (MDGA) is a bifunctional monomer possessing two epoxy groups (glycidyl groups) and two amine groups. It is commonly used as a monomer in the production of thermosetting polymers, particularly epoxy resins. MDGA-based epoxy resins can exhibit desirable properties such as high strength, chemical resistance, and thermal stability, which makes them suitable for a wide range of applications such as adhesives, coatings, composites, and electronic encapsulation.[1][2][3]

Zastosowanie

4,4′-Methylenebis(N,N-diglycidylaniline) can be used:
  • As a starting material to synthesize UV-curable tetra-functional epoxy acrylate (EA4), which is used as a crosslinker for UV-curable resins.
  • In the synthesis of bismaleimide/diallyl bisphenol A (BMI/DBA)–epoxy interpenetrating network resins, which have potential applications in the aerospace and automotive industries because of their high thermal stability and low activation energy.
  • As a crosslinking agent in the production of biocompatible materials, such as hydrogels and other tissue engineering scaffolds. Its ability to form strong and stable crosslinks makes it valuable in the creation of medical devices, implants, and drug delivery systems. Additionally, it is utilized in the synthesis of biocompatible polymers and materials with tailored properties for biomedical applications.
4,4′-Methylenebis(N,N-diglycidylaniline) can be also used as a precursor to synthesize:
  • Poly(hexamethylene biguanide) based polymer networks which are applicable as catalysts for the transesterification of vegetable oils.
  • Tetra-functional epoxy-acrylate UV curable resins.
It can also be used as a crosslinker to functionalize carbon nanotubes to improve their mechanical strength.

Contact dermatitis, 11(2), 80-82 (1984-08-01)
An outbreak of dermatitis occurred in an aircraft factory using epoxy resin composite material. Of 25 operatives, 14 gave positive patch test reactions to the composite material and/or diglycidylether of bisphenol A (DGEBA), tetraglycidyl-4,4'-methylene dianiline (TGMDA), and o-diglycidyl phthalate.

Epoxy-anhydride vitrimers are covalent adaptable networks, which undergo associative bond exchange reactions at elevated temperature. Their service temperature is influenced by the glass transition temperature (Tg) as well as the topology freezing transition temperature (Tv), at which the covalent bond

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
