一般描述

Dabco® 33-LV作为叔胺催化剂，在聚合物应用中具有多种用途。它广泛用作催化剂，通过异氰酸酯和多元醇之间的反应生产柔性和刚性聚氨酯泡沫。它可以帮助控制凝胶时间，改善泡沫上升，并优化最终聚氨酯泡沫的物理性质。这些泡沫通常用于绝缘材料、汽车应用、建筑和包装应用。此外，DABCO® 33-LV可以在各种基材上形成自组装单层（SAM），使其成为聚合物领域中的有用双齿配体。

Dabco®33-LV (Db)是一种凝胶催化剂和双齿配体，可以在各种基材上形成自组装单层（SAM）。它可使表面功能化并固定表面原子。[1][2]

应用

Db可用于：


  • 作为凝胶催化剂，促进柔性和刚性聚氨酯泡沫、微孔泡沫、涂层和弹性体生产中的凝胶反应。用于加速异氰酸酯-多元醇反应。
  • 在通过静电纺丝合成阴离子交换膜（AEM）的过程中，有助于聚合物之间的交联，维持膜的机械稳定性。AEM可进一步用于燃料电池、水电解、氧化还原液流电池和电解槽。
  • Db可用于制备环氧基大豆油，以形成聚氨酯泡沫。

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.
