Abstract

The invention relates to a crosslinkable composition containing reactive polymers selected from among (i) prepolymers having reactive NCO groups or (ii) polymers which have reactive silane groups, optionally further additives and at least one metal-based catalyst, wherein the composition contains up to 10% by weight of retarding substance selected from among cyclic α-hydroxy ketones and/or triphenols having three adjacent OH groups.
