Reactive hot melt adhesives

  • Moisture curable hot melts, based on SUPRASEC MDI* and IROSTIC M thermoplastic polyurethane (TPU) from Huntsman Polyurethanes, represent a class of high-performance adhesives.
  • They combine the advantages of thermoplastic hot melts with fast strength development and the ability to crosslink liquid reactive systems.
  • The hot melt character enables the enduser to achieve a fast processing of the laminated parts, whereas the crosslinking enhances the resistance against the environment and the surroundings.
  • The major raw materials for manufacturing reactive hot melts are polyester polyols, MDI or MDI-derivatives and thermoplastic resins.
  • Huntsman Polyurethanes offers an extensive range of SUPRASEC isocyanates and IROSTIC M thermoplastic polyurethanes for the adhesives market. Both product lines offer unique building blocks for tailoring moisture-curable adhesives.
  • MDI and MDI-derivatives are needed to bring reactivity to the reactive hot melt, whereas the addition of IROSTIC TPU enhances the green strength of the adhesive.
