Beschreibung
Zusammenfassung:	The present invention relates firstly to adducts of the formula (I) which are obtainable from the reaction of an oligomeric aliphatic polyisocyanate and a compound of the formula HX-R1. Secondly the invention relates to one-component or two-component compositions which comprise such adducts of the formula (I). The adducts of the formula (I) find a use as adhesion promoters and are suitable in particular for use in elastic adhesives and sealants. The cured one-component or two-component compositions exhibit excellent paint adhesion in tandem with high extensibility.
