Stabilized aqueous crosslinker dispersions

摘要

The present invention relates to a water-dispersible crosslinker composition containing A) at least one hydrophilically-modified, blocked polyisocyanate, B) at least one stabilizing agent containing a) at least one amine containing a structural unit corresponding to formula (I) which does not contain hydrazide groups, b) at least one compound containing a structural unit corresponding to formula (II) -CO-NH-NH- (II) and c) optionally a stabilizing component other than a) and b), and C) optionally an organic solvent. The present invention also relates to an aqueous solution or dispersion containing this crosslinker composition, to aqueous coating compositions containing this crosslinker composition and to glass fibers coated with this coating composition.
