Abstract
(DE)
Es werden Polyurethan-Zusammensetzungen mit einem niedrigen Anteil an monomeren Diisocyanaten beschrieben. Vorzugsweise werden hierfür trifunktionelle Isocyanate eingesetzt, die ggf. mit einem monofunktionellen Abbrecher in ihrer Funktionalität auf 3,0 ± 0,7 reduziert werden. Hierdurch enthalten die Zusammensetzungen erheblich geringere Mengen an leichter flüchtigen Isocyanaten. Diese Zusammensetzungen eignen sich zur Verwendung als reaktive Schmelzklebstoffe, Kaschierklebstoffe, Kleb-/Dichtstoffe, Primer sowie zur Herstellung von Schaumkunststoffen aus Einweg-Druckbehältern (Aerosol-Dosen). Durch den niedrigen Gehalt an flüchtigen monomeren Diisocyanaten läßt sich der Aufwand für Arbeitsschutzmaßnahmen signifikant reduzieren, außerdem wird die Entsorgung von in den Gebinden verbleibenden Resten erheblich erleichtert.
(EN)
The invention concerns polyurethane compositions having a low content of monomer diisocyanates. Preferably used for this purpose are trifunctional isocyanates whose functionality is optionally reduced to 3.0 ± 0.7 by means of a monofunctional break-down agent. The compositions consequently contain considerably smaller amounts of highly volatile isocyanates. These compositions are suitable for use as reactive fusion adhesives, bonding adhesives, adhesives/sealants and primers and also for producing foamed plastics from non-returnable pressurized containers (aerosol cans). Owing to the low content of volatile monomer diisocyanates, the expenditure on protective operating measures can be significantly reduced and additionally the disposal of residues remaining in containers is considerably facilitated.
(FR)
L'invention concerne des compositions de polyuréthanne à faible teneur en diisocyanates monomères. A cet effet, on utilise de préférence des isocyanates trifonctionnels dont la fonctionnalité est éventuellement réduite à 3,0 ± 0,7 au moyen d'agents de rupture monofonctionnels. Les compositions contiennent alors des proportions nettement plus faibles d'isocyanates fortement volatils. Ces compositions peuvent être utilisées sous forme d'adhésifs réactifs à fusion, d'adhésifs de contrecollage, d'adhésifs et de matériaux d'étanchéité, de primaires ainsi que dans la fabrication de matières plastiques expansées à partir de récipients sous pression jetables (bombes aérosol). La faible teneur en diisocyanates monomères volatils permet de réduire de façon significative les frais liés aux mesures de sécurité du travail, et facilite en outre considérablement l'élimination des résidus dans les contenants.
