  • Latent-reactive hot-melt adhesive composition
    Patent number: 9902887
    Abstract: A latent-reactive hot-melt adhesive composition comprising a) at least one first thermoplastic polymer, which is monofunctionally reactive to NCO groups and has a high tensile strength, b) at least one second NCO-reactive polymer and/or oligomer, polymer miscible with the first polymer a), which is at least di-functionally, preferably tri- or multifunctionally, reactive to NCO groups and has a melting temperature (Tm), which is lower than the melting temperature (Tm) of polymer a), and is in liquid form, c) at least one solid, surface deactivated di- and/or polyisocyanate, d) optionally one or more further thermoplastic polymer(s) which does not or do not react to NCO groups. Such compositions have significantly improved mechanical characteristics.
