Beschreibung
Zusammenfassung:	The present invention is directed to a polyisocyanate containing a) polyisocyanates containing isocyanurate groups and corresponding to formula 1 (see formula 1) wherein R represents the residue obtained by removing one of the isocyanate groups from 4-isocyanantomethyl-1,8 octamethylene diisocyanate, optionally in admixture with b) unreacted 4-isocyanantomethyl-1,8-octamethylene diisocyanate, c) higher homologs of the polyisocyanates set forth in formula 1 containing more than one isocyanurate group and d) a polyisocyanate containing allophanate groups. The present invention also relates to the use of these polyisocyanate mixtures, optionally in blocked form, as an isocyanate component in one- or two-component coating compositions.
