Moisture-curing composition with good adhesive properties

A moisture-curing composition which is liquid or pasty at room temperature, comprising

• at least one polyether urethane polymer P1 containing isocyanate groups and having a content of at least 80% by weight of 1,2-propyleneoxy units in the polyether segment, and
• at least one room temperature liquid, hydrophobic polymer P2 containing isocyanate groups, obtained from the reaction of at least one monomeric diisocyanate and a hydrophobic diol having an OH number in the range from 28 to 120 mg KOH/g,
• wherein polymers P1 and P2 are prepared separately from one another and polymer P1 and polymer P2 are present in a weight ratio in the range from 70/30 to 98/2, and
• wherein the hydrophobic diol for the preparation of polymer P2 is selected from the group consisting of dimer fatty acid-based polyester diols and poly(1,2-butylene glycol).
