Phthalate-free isocyanurate preparations

An isocyanurate preparation containing isocyanate groups and having a viscosity <30 000 mPas at 23° C. and having a content of free diisocyanatotoluene ≦1.0% by weight (total of all diisocyanatotoluene isomers), comprising

• A) from 15 to 50% by weight of isocyanurates which contain isocyanate groups and which have been prepared from a mixture of isomeric diisocyanatotoluenes comprising from 65 to 95% by weight of 2,4-diisocyanatotoluene and from 5 to 35% by weight of 2,6-diisocyanato-toluene with catalysis by phenolic catalysts containing dialkylamino groups and in the absence of aliphatic hydroxy and/or urethane groups, and
• B) from 85 to 50% by weight of phthalate-free plasticizers containing a mixture of phenyl alkanesulphonates.
