A moisture-curing, one-component polyurethane composition, containing at least one isocyanate group-containing polyether urethane polymer obtained by reacting at least one polyisocyanate with at least one polyether polyol; at least one isocyanurate-containing trimer of 1-isocyanato-3,3,5-trimethyl-5-isocyanatomethyl cyclohexane or 1,6-hexane diisocyanate in a quantity of between 1 and 4 percent by weight in the composition; at least one polyether with blocked hydroxyl groups, which is free of isocyanate groups, as a plasticiser, in a quantity of more than 5 percent by weight in the composition. Where moisture is excluded, the moisture-curing polyurethane composition has good storage stability, good processability and good thermal stability, and surprisingly good adhesive effect on highly scratch-resistant, hydrophobic automotive paints, and no pretreatment with adhesion promoters, primers or activators is needed. It is especially suitable for use as an elastic adhesive in the production of means of transport.
