A two-component adhesive or sealant composition consists of a first component (K1) comprising a prepolymer P, which displays an isocyanate group, and an acceleration component (K2). The said acceleration component (K2) displays a catalyst, which catalyzes the reaction of isocyanate groups and which is a lead, zinc, or iron (III) complex, as well as compounds displayed on isocyanate-reactive groups that are at most 1% by weight. In particular, adhesives with a high cure velocity and good adhesion can be obtained and adapted very easily to ambient conditions.
