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.

General description
Application
- As a cross-linking agent to synthesize biodegradable poly (1,3-trimethylene carbonate) (PTMC) networks with improved creep resistance and thermal stability. PMTC networks find application in the field of soft tissue engineering.
- As a monomer precursor to prepare light-curing dental composites via photopolymerization.
- To fabricate polymer-dispersed liquid crystal(PDLC) films with low driving voltage, moderately high contrast ratio, and fast response time. These PDLC films are utilized in optoelectronic devices such as OLEDs, FET, and solar cells.
- As a monomer mixture to prepare 3D bioprinting resins viaphotopolymerization.

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
