General description

Terminal secondary tetrahydroxy-functional oligomer.

Application

Hard and soft surface cleaners, defoamers in coatings and water treatment. Lubricant in metal working, anti-foaming aid and extender for linear and cross-linked polyesters and polyurethanes.

Features and Benefits

Ethylenediamine tetrakis(ethoxylate-block-propoxylate) tetrol exhibits surface activity that varies with the EO/PO ratio. It offers lower foaming properties, enhanced defoaming capabilities, and reduced gelling tendencies compared to typical surfactants. Additionally, its terminal secondary hydroxyl groups exhibit lower reactivity and acidity than primary hydroxyl groups found in other surfactants, making it a versatile choice for various applications.

Questions

1–3 of 3 Questions  
  1. I would like to clarify the identity of this product: Is it Tetronic 904 or Tetronic 90R4? The displayed molecular structure appears to be Tetronic 90R4, but it lists Tetronic 904 under its Synonym(s).

    1 answer
    1. The identity of this product has been inconsistent in the past. Initially, Tetronic 90R4 was purchased, but later Tetronic 904 was sourced. Based on the appearance, the current product aligns with Tetronic 90R4.

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

    1 answer
    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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

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

    1 answer
    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
