Product description
Isocyanurate resin from isophorone diisocyanate (IPDI).Desmodur® Z 2589 is a micronized colorless to slightly yellowish isocyanate resin in powdered form.
Applications
After suitable deactivation Desmodur® Z 2589 can be used in combination with Dispercoll® U as a curing component for one-component latent-reactive polyurethane dispersion adhesives, for the formulation of latent-reactive adhesive layers or for the formulation of latent-reactive film. Desmodur® Z 2589 is soluble and can be diluted in polar aprotic solvents such as esters, ketones like butyl acetate, methyl ethyl ketone and methoxy propyl acetate and in aromatics. Compatibility with the listed solvents is generally good but the storage stability of the respective solutions should be tested. Only PU grade solvents should be used (max. 0.05 % water, free of reactive groups like hydroxyl or amino groups).Desmodur® Z 2589 can also be used as a curing component for 2-component solvent-based adhesives.Desmodur® Z 2589 is currently listed in all adhesives-relevant foodstuffs regulations worldwide. At EU level new foodstuffs regulations with new migration thresholds are currently being prepared. An up-to-date statement on the relevant boundary conditions (SML and DWL* values) is available on request. * SML = Specific Migration Limit** DWL = Drinking Water Limit
