Beschreibung
Zusammenfassung:	A moisture-curing composition that is liquid at ambient temperature and optionally highly viscous, containing: at least one polyether urethane polymer (P1) containing isocyanate groups and having a content of at least 80% by wt. 1,2-propyleneoxy units in the polyether segment, and at least one hydrophobic polymer (P2) containing isocyanate groups and being liquid at ambient temperature, obtained by reacting at least one monomeric diisocyanate and a hydrophobic diol having an OH-number ranging between 28 and 120 mg KOH/g, the polymers P1 and P2 being produced separately and said polymers P1 and P2 having a weight ratio ranging between 70/30 and 98/2.
