General description
Application
(2-Ethyl-2-(hydroxymethyl)-1,3-propanediol polymer with (chloromethyl)oxirane is used in the synthesis of azidated trimethylolpropane triglycidyl ether for the preparation of polyether polyol based hyperbranched polyurethanes.[3] It can be coated on polycarbonated chips for improving chemical resistance from different organic solvents.[4] Cross-linking of (2-Ethyl-2-(hydroxymethyl)-1,3-propanediol polymer with (chloromethyl)oxirane can be done with poly(4-venylphenol) (PVP) for the preparation of organic field effect transistors (OFETs).[5][6]
Additive in fast-setting adhesives, low temperature curing coatings and hard, abrasion resistant castings and decoupage systems.
Features and Benefits
Reduces viscosity but retains high epoxide level, imparts hardness and toughness to epoxide polymers. Improves solubility/compatibility characteristics of highly aromatic epoxy systems.

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 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.
