Curable composition, useful as an adhesive-, a sealant- or a coating material, comprises polyether or polyacrylic acid ester with silyl end group, an organotin compound and a compound exhibiting at least two functional groups

摘要

Curable composition comprises: (a) at least one polyether and/or at least one polyacrylic acid ester with at least one silyl end group (I); (b) at least one organotin compound; and (c) at least one compound exhibiting at least two functional groups including carboxyl-, carbonyl-, hydroxyl groups or nitrogen atoms, which are a part of a ring system with an aromatic nature. Curable composition comprises: (a) at least one polyether and/or at least one polyacrylic acid ester with at least one silyl end group of formula (-A n-R-SiXY1Z) (I); (b) at least one organotin compound; and (c) at least one compound exhibiting at least two functions, including carboxyl-, carbonyl-, hydroxyl groups or nitrogen atoms, which are part of a ring system with an aromatic nature. A : divalent binding group; R : divalent 1-12C hydrocarbon (optionally comprises heteroatom); X, Y1, Z : 1-8C alkyl, 1-8C alkoxy or 1-8C acyloxy; and n : 0 or 1. An independent claim is also included for producing the curable composition comprising mixing the components (a)-(c) and an adhesion promoter with each other.
