One-component isocyanate-crosslinking two-phase compositions |
摘要 |
The present invention relates to surface-deactivated solid isocyanates obtained by surface reaction of finely dispersed solid isocyanates with mono- or polyamines that have anionic groups or groups capable of anion formation and have primary and/or secondary amino groups. The present invention also relates to a process for the preparation of the solid, surface-deactivated isocyanates by dispersing finely divided, solid isocyanates in a liquid medium and reacting them with mono- or polyamines having primary and/or secondary amino groups and having anionic groups or groups capable of anion formation. Finally, the present invention relates to compositions containing the solid, deactivated isocyanates according to the invention and isocyanate-reactive dispersions of homo- and co-polymers of olefinically unsaturated monomers and/or polyurethane dispersions.
