Abstract
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 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.
