General description

Neopentyl glycol diglycidyl ether (NGDE) is a low-toxic epoxy molecule with two epoxy pendant groups at the end of the long chain. It has excellent reactivity, low viscosity, and cross-linking properties. It facilitates the resin with high strength and impact resistance. It is used as a precursor to synthesize hydrogels for drug delivery, dental materials, coating, and adhesives for medical devices and tissue engineering. It is also used as a solid matrix to fabricate light-emitting devices like OLEDs.

Application

Neopentyl glycol diglycidyl ether can be used,



  • As a cross-linking agent to prepare Pullulan/polydopamine hydrogels for selective adsorption of pollutant cationic dyes.[1]
  • As a monomer to synthesize gel polymer electrolytes for Li-ion batteries via cationic ring-open polymerization.[2]
  • As a precursor for the synthesis of hybrid epoxy methacrylate resins cationic and free-radical photopolymerization. These epoxy resins can be used as anti-corrosion and decorative coatings.[3]
  • To synthesize epoxy nanocomposites for fabrication of light-emitting devices.[4]

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.
      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
