Reactive hot melt adhesives combine the advantages of polyurethane hot melts with one-component polyurethane adhesives. They provide fast initial strength build-up and show excellent mechanical property retention at high temperatures, yet can be applied at intermediate temperatures. They have applications in the bookbinding, woodworking, packaging, automotive and construction industries.
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.
