Abstract:
The present invention relates to a novel process for preparing polyisocyanates having isocyanurate groups by a partial trimerization of (cyclo)aliphatic diisocyanates in the presence of at least one trimerization catalyst from the group of ammonium salts of lactames and to the use of the thus obtainable polyisocyanates having isocyanurate groups as a polyisocyanate component in polyurethane coatings.
