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.

Niedawny popyt na pojazdy elektryczne i hybrydowe, w połączeniu z obniżką cen, spowodował, że akumulatory litowo-jonowe (LIB) stały się coraz bardziej popularną formą technologii akumulatorów.
Hybrid organic-inorganic sol-gel materials containing silica were first called “ORMOSILs” in 1984.
Recent demand for electric and hybrid vehicles, coupled with a reduction in prices, has caused lithium-ion batteries (LIBs) to become an increasingly popular form of rechargeable battery technology.

How to coat the product APTES (741442) on high density polyethylene surface?
1 answer-
The high-density polyethylene surface requires thorough cleaning with a solvent like isopropyl alcohol or ethanol to eliminate contaminants. To enhance adhesion, the surface can be treated to increase roughness through plasma treatment or by using sandpaper to create a micro-rough texture. After cleaning, prepare a solution by dissolving this product in a suitable solvent, typically ethanol or toluene. A common concentration range is 1-5% (w/v), depending on the desired coating thickness. Apply the solution to the polyethylene surface using methods such as spraying, dipping, or brushing. Allow the surface to cure at room temperature or by applying gentle heat (60-80°C) in an oven.

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

How to coat the product APTES (741442) on a Si wafer surface?
1 answer-
To coat APTES (741442) on a Si wafer surface:
1. Prepare a 1.6% APTES solution in toluene.
2. Soak the Si wafer in the solution for 2.5 hours.
3. Rinse the wafer using ethanol and water three times.
It's important to note that no initiator is needed. Varying the concentration and soaking time can result in different thicknesses of the APTES layer, but a layer that is too thick may exfoliate quickly.Helpful?
