Abstract
(DE)
Die vorliegende Erfindung betrifft eine Polyisocyanatzusammensetzung, umfassend eine Mischung aus ≥ 60 Gew.-%, bezogen auf das Gesamtgewicht der Mischung, mindestens eines Polyisocyanats auf Basis von Pentamethylendiisocyanat und ≤ 40 Gew.-%, bezogen auf das Gesamtgewicht der Mischung, mindestens eines Polyisocyanats auf Basis eines cycloaliphatischen Diisocyanats und/oder mindestens eines Polyisocyanats auf Basis von Pentamethylendiisocyanat und wenigstens einem cycloaliphatischen Diisocyanat, wobei die Polyisocyanatzusammensetzung einen Restmonomerengehalt an monomeren Diisocyanaten unter 0,5 Gew.-%, bezogen auf das Gesamtgewicht der Polyisocyanatzusammensetzung, aufweist.
(EN)
The present invention relates to a polyisocyanate composition, comprising a mixture of ≥ 60 wt.%, relative to the total weight of the mixture, of at least one polyisocyanate based on pentamethylene diisocyanate and ≤40 wt.%, relative to the total weight of the mixture, of at least one polyisocyanate based on a cycloaliphatic diisocyanate and/or of at least one polyisocyanate based on pentamethylene diisocyanate and at least one cycloaliphatic diisocyanate, the polyisocyanate composition having a residual monomer content of monomer diisocyanates below 0.5 wt.%, relative to the total weight of the polyisocyanate composition.
