Zastosowanie

The uniqueness of D.E.R. 332 epoxy resin is reflected in its maximum epoxide equivalent weight of 178. Because of its high purity and lack of polymer factions, samples embedded using D.E.R. 322 have uniform performance, exceptionally low viscosity and color; and improved elevated temperature properties.[1][2]

Przestroga

Crystallizes very slowly at room-temperature; can be melted by heating up to 50-55 °C

Questions

1–3 of 3 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.

  3. If you order an epoxy resin, does it include a hardener?

    1 answer

    1. The product D.E.R.™ 332 refers to the epoxy resin component only. It does not include a hardener. Epoxy resins generally require a separate hardener or curing agent to initiate the curing process and achieve the desired properties.
