일반 설명

Dimer acid, hydrogenated is a fatty acid with 36 carbon atoms. It consists of a cyclohexene ring which can be synthesized by clay-catalyzed dimerization at 230-250°C.[1][2]
Improves flexibility, toughness, impact resistance, dyeability and hydrolytic stability of polymers.

애플리케이션

Comonomer in polyesters, polyamides and polyurethanes.
Dimer acid, hydrogenated can be used as a corrosion inhibitor for the protection of lead metal substrates.[3] It can also be used in polyamide based hot melting adhesives as a thermoplastic polymer for electronic boards, textiles and packaging systems.[4]

질문

1–2 / 2 질문  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 답변

    1. 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.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 답변

    1. 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
