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.

Description générale
Application
PDMS is a material of choice for ophthalmic applications due to its high mechanical strength, transparency, and oxygen permeability. It can be used as a prepolymer to prepare a glucose permeable interpenetrating network of PDMS and poly (N-isopropyl acrylamide (PNIPAAM). These networks can be used in ophthalmic applications.
PDMS can also be used to synthesize fire and heat-resistant polyurethane-PDMS hybrids. The addition of PDMS provides low flammability and thermal stabilization to polyurethane under pyrolytic conditions.
PDMS is used as an additive to prepare TEOS-based stone protective hybrid crack-free xerogels. The addition of PDMS accelerates the gelling process and helps to achieve effective stone protection.

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?
