Isocyanate group-containing isocyanurate compositions have a viscosity below 30,000 mPas at 23[deg] C and a maximum content of free diisocyanatotoluol of 1.0 wt%. They contain 15 - 50 wt% of isocyanate group-containing isocyanurate; and 85 - 50 wt% of a plasticizer containing an alkanesulfonic acid arylester.The isocyanurate is produced from a mixture of 65 - 95 wt% 2, 4-diisocyanatotoluol and 5 - 35 wt% of 2, 6- diisocyanatotoluol using a phenolic catalyst which contains dialkylaminogroups in the absence of aliphatic hydroxy- and/or urethane groups. Independent claims are included for 1 use of the compositions as adhesion promoters for plasticized polyvinyl chloride coating agents 2 coatings for textiles which contain the compositions; and 3 substrates coated using the compositions. |
