 Features/Applications .                                  
      Appropriately deactivated DesmodurZ 2589 can be used in combination with Dispercoll U as a curing one-component latent reactive polyurethane dispersion adhesive for latent reactive adhesive layers or for latent reactive film formulations. DesmodurZ 2589 is water soluble and can be diluted in aprotic polar solvents such as esters such as butyl acetate, methyl ethyl ketone, ketone methoxy propyl acetate and aromatic hydrocarbons. Compatibility with commercial solvents is generally good, but the respective storage stability needs to be tested. Polyurethane grade solvents should be used (less than 0.05% water, no reactive groups such as hydroxyl or amino groups). DesmodurZ 2589 can also be used as a curing agent for two-component solvent-based adhesives. DesmodurZ 2589 is currently compliant with global regulations for food adhesives. Regulations on food migration thresholds at EU level are currently under preparation. Up-to-date statements on relevant boundary conditions (SML* and DWL** values) are available upon request.
