The invention aims to allow a curable composition to have an extended working phase followed by a short time period in which said compound becomes fully cured. This is achieved by the provision of a curable composition comprising the following components: a) at least one polyether and/or at least one polyacrylic acid ester with at least one reactive silyl group as an end-group; b) at least one organotin compound; and c) at least one compound that does not contain any tin or silicon atoms and that has at least two functional groups. Said groups are selected from the following: carboxy, carbonyl or hydroxy groups, or nitrogen atoms that are part of a ring system with aromatic character. In addition, the invention relates to a method for producing such a composition, and to the use thereof as an adhesive, a sealant or as a coating material.
