    • 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.

    • Aim of the invention is to implement low viscosity prior to curing along with good elasticity after curing and a broad adhesion spectrum in a solvent-free and water-free curable composition. This aim is achieved by using at least one polymer A, obtainable by converting a polyether and at least one ethylenically unsaturated silane, wherein the ethylenically unsaturated silane has at least one hydrolysable group on the silicon atom, in the presence of a radical starter. The invention further relates to a method for producing a solvent-free and water-free curable composition, characterized in that at least one polymer is produced by converting a polyether and at least one ethylenically unsaturated silane having at least one hydrolysable group on the silicon atom, in the presence of a radical starter, and the polymer so obtained is mixed with further components of the composition. The invention further relates to the use of the curable composition according to the invention, or of a composition produced by means of the method according to the invention, as an adhesive, sealant, or coating agent.
