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.

应用
- 压敏胶黏弹性：本研究考察了交联密度和线性粘弹性对胶粘剂剪切破坏的影响，展示了乙酰丙酮铝在提高工业胶粘剂性能和耐久性方面的作用（Arrowood et al., 2023）。
- PVC热稳定剂：讨论了利用乙酰丙酮铝促进的机械化学方法制备镁铝水滑石，以及其作为聚氯乙烯热稳定剂的应用，强调了其在提高聚合物热稳定性方面的重要性（Jiang et al., 2020）。

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
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.
