Beschreibung
Zusammenfassung:	The present invention relates to a polyisocyanate composition comprising a formation component having isocyanate groups, the isocyanate groups having been reacted to an extent of ≥98% with at least one CH-acidic compound, characterized in that the formation component consists to an extent of ≥51% by weight of at least one polyisocyanate based on pentamethylene 1,5-diisocyanate having a content of isocyanurate trimer of ≤60 area %, based on the total weight of the polyisocyanates based on pentamethylene 1,5-diisocyanate, and the remaining proportion up to 100% by weight of the total amount of polyisocyanates present in the formation component consists of at least one aliphatic or cycloaliphatic polyisocyanate. The present invention further provides a one-component system comprising the polyisocyanate composition, a process for producing a coating on a substrate, and the coatings obtainable from the one-component system.
