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.

一般說明
應用
由于其高机械强度、 透明度和氧渗透性， PDMS是眼科应用的首选材料。 它可作为预聚物用于制备 葡萄糖可渗透的PDMS和(N-n-异丙基丙烯酰胺 的互穿网络（PNIPAAM)。这种网络可用于眼科应用。
PDMS也可用于合成 耐火、耐热的聚氨酯-PDMS杂合体。PDMS的加入 为聚氨酯带来了热解条件下的低可燃性和热稳定性。
PDMS可作为添加剂用于制备 TEOS基石头保护杂合体 无裂纹干凝胶PDMS的加入加速了胶凝过程并 有助实现有效的石头保护。

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
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

Hello, good afternoon, excuse me, I have a question about PDMS hydroxyl terminated. What curing agent is used to have PDMS films?
1 answer-
Generally, Sylgard 184 is the curing agent for PDMS, for example, 761028:https://www.sigmaaldrich.com/product/aldrich/761028
The product contains two components. One is the curing agent. The other is vinyl-terminated PDMS. Unfortunately, the curing agent is not sold separately.Helpful?
