General description
Pentaerythritol tetraacrylate (PETA) is a hydrophobic tetrafunctional monomer that is majorly used as a crosslinking agent that facilitates an improvement in the surface morphology of the polymeric material. It can be synthesized by the suspension of pentaerythritol in the solution of triethylamine and dichloromethane. PETA can be used in coatings, adhesives, sealants, surface coating, and composites. Its reactivity and ability to form densely crosslinked networks make it an essential component in the formulation of UV-curable materials. PETA is also used as a key component in the preparation of biocompatible polypeptide-based interpenetrating network (IPN) hydrogels, which find applications in tissue engineering, drug delivery systems, or biomedical devices.
Application
Pentaerythritol tetraacrylate can be used as a monomer:
- To synthesize polymer electrolytes for the fabrication of lithium-sulfur batteries.
- In the formulation of UV-curable epoxy acrylate coatings, to improve their mechanical properties and performance.
- To prepare multifunctional silicone acrylate prepolymers for use in UV-curable coatings, to improve their mechanical and anti-oxygen inhibition properties.
- In the UV-curable ink formulations.

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.

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
