Descripción general

Dabco® 33-LV, as a tertiary amine catalyst, has various uses in polymer applications. It is widely utilized as a catalyst in the production of flexible and rigid polyurethane foams via the reaction between isocyanates and polyols. It helps control the gel time, improve foam rise, and optimize the physical properties of the final polyurethane foam. These foams are commonly used in insulation materials, automotive applications, construction, and packaging applications. Additionally, DABCO® 33-LV can form a self-assembled monolayer (SAM) on a variety of substrates, making it a useful bidentate ligand in the field of polymers.

Dabco®33-LV (Db) is a gelling catalyst and a bidentate ligand that forms a self-assembled monolayer (SAM) on a variety of substrates. It functionalizes the surface and immobilizes the surface atoms.[1][2]

Aplicación

Db can be used:


  • As a gel catalyst to promote the gel reaction in the production of flexible and rigid polyurethane foams, microcellular foams, coatings, and elastomers. It is used to accelerate the isocyanate-polyol reaction.
  • In the synthesis of anion exchange membranes (AEMs) via electrospinning, contributing to the crosslinking between the polymers and the mechanical stability of the membrane. AEMs are further used in fuel cells, water electrolysis, redox flow batteries, and electrolyzers.
  • Db can be used in the preparation of epoxy based soybean oil for the formation of polyurethane foams.

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.
