Product Introduction
TMXDI(META) aliphatic isocyanate monomer contains two tertiary fatty alcohol diisocyanate functional groups. This functionality provides unique properties compared to primary and secondary isocyanates.
TMXDI* monomers are used to synthesize solvent-free polyurethane dispersions. These dispersions can be engineered for water-based adhesives, coatings and inks with light stability, adhesion, flexibility and rigidity.

<span��When good ductility is maintained, dispersions synthesized from TMXDI monomers constitute unique coatings with flexibility. The dispersion based on the characteristics of TMXDI monomer can be made into soft and elastic coatings, as well as coatings with hardness close to that of automotive topcoats. Achieving the specified stiffness depends on choosing the correct host polyester resin and varying the NCO/OH ratio, as well as the amount of carboxylic acid functional groups and short chain diols. When it is desired to use these dispersions to form hard paint films, it is necessary to add the relevant solvent and resin mixture. Coatings based on dispersions of TMXDI monomers have uniquely good substrate adhesion. Because these dispersions are thermoplastic, the addition of a crosslinker is recommended when solvent resistance is required in the paint film. Adhesive Application Dispersion synthesized from TMXDI monomer Physical properties provide a lower thermal activation temperature than dispersions synthesized from isophorone diisocyanate or hydrogenated benzhydryl isocyanate. In addition to the lower activation temperature, the adhesive activation temperature remains constant over time. Low heat activation and good adhesion to flexible substrates allow TMXDI-based solvent-free dispersions to be applied to temperature-sensitive plastic substrates and flexible film adhesives. Ink Application Due to the adhesion of TMXDI monomer-synthesized dispersions on flexible plastic substrates, it is a good choice for water-based ink binders. closed product TMXDI (META) aliphatic isocyanate reacts with typical blocked isocyanates to form one-component thermosetting coatings. For immobilized blocking agents, tertiary isocyanate functional groups specify deblocking temperatures 10-15°C lower than primary and secondary isocyanates.
