TMXDI Aliphatic isocyanate monomer containing two tertiary aliphatic diisocyanate groups 002778-42-9 Cytec PU - Isocyanates ADHESIVE >> Hot-melt ADHESIVE >> Reactive system ADHESIVE >> Water-based TMXDI (META) aliphatic isocyanate monomer contains two tertiary aliphatic diisocyanate groups. This functionality provides unique properties as compared to primary and secondary isocyanate containing monomers. TMXDI1 monomer is used to prepare solvent-free polyurethane dispersions. These dispersions can be designed to provide adhesion, flexibility, and toughness to light-stable, waterborne adhesives, coatings, and inks. Dispersions prepared from TMXDI monomer provide lower heat activation temperatures than can be obtained from the same dispersion prepared from either isophorone diisocyanate or hydrogenated methylene diphenylene isocyanate. In addition to lower activation temperature, the activation temperature of applied adhesive remains constant over time. The combination of low heat activation and good adhesion to flexible substrates makes solvent-free dispersions based on TMXDI of interest for applications involving temperature sensitive plastic substrates and flexible films.
