General description

Isophorone diisocyanate (IPDI) is an aliphatic diisocyanate that is majorly used as a curing agent by forming −NCO linkages. It is mainly utilized in the preparation of various polyurethane products for a variety of high-performance coatings for automotive and industrial applications, medical devices, upholstery, insulation, and packaging applications, and in the manufacture of adhesives, sealants, and binders. It provides UV resistant films due to the presence of the aliphatic ring.

Application

IPDI is primarily used as a diisocyanate monomer in the production of polyurethane resins and elastomers. IPDI is highly reactive and can be used to produce polymer products with varying properties, ranging from rigid to flexible. Some of the primary uses of IPDI in polymer industries include:
  • Production of polyurethane coatings for automotive and industrial applications.
  • Synthesis of polyurethane elastomers used in medical devices and sports equipment.
  • Production of polyurethane foams used in upholstery, insulation, and packaging applications.
  • Use in the manufacture of adhesives, sealants, and binders.
  • In the synthesis of bridged silsesquioxane(BSQ) by sol-gel polycondensation with 3-aminopropyltriethoxysilane. The polymer of BSQ can be used to prepare the moisture-resistant film for UV filters.
  • As a healing agent in the preparation of polyurethane microcapsules by interfacial polymerization.
  • As a monomer in the synthesis of highly monodispersed polyurea microspheres via precipitation polymerization.

Questions

1–2 of 2 Questions  

  1. 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

  2. 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
