Abstract

The invention relates to compositions comprising at least one polyurethane prepolymer A with isocyanate terminal groups and at least one polyaldimine B. The polyurethane prepolymer A is produced from at least one polyol A1, optionally at least one polyol A2, in addition to polyisocyanates. The polyol A1 is a linear polyoxyalkylene polyol and has a degree of unsaturation of <0.04 mEq/g and the polyol A2 is present in a quantity of between 0 and 30 wt %, preferably between 0 and 20 wt % and in particular between 0 and 10 wt. %, in relation to the total quantity of A1+A2. In addition to the aforementioned components, a composition according to a preferred embodiment can also contain one or more of the following components: plasticizers, solvents, fillers, pigments, catalysts, rheology modifiers such as e.g. thickeners, coupling agents, dehydrators, antioxidants, light-protection agents and other conventional additives in the polyurethane industry.
