Abstract: The present invention concerns a two-part curable composition comprising: ? a first part (component A) comprising at least 51% by weight based on the total weight of the first part, of one or more cyanoacrylate monomer(s), provided that at least one of the cyanoacrylate monomer(s) is a cyanoacrylate monomer comprising a group —X—O—Rb wherein X is a linear or branched alkylene radical optionally interrupted with one or several oxygen atom(s), and Rb is an alkyl group; ? a second part (component B) comprising: at least one Michael acceptor M selected from the group consisting of (meth)acrylic monomers, (meth)acrylic functionalized oligomers, (meth)acrylic functionalized resins, and mixtures thereof, provided that at least one of the Michael acceptor(s) M comprises at least one group of formula -0(CHRa—CH2O)n— where n ranges from 1 to 10 (Michael acceptor M1), and Ra represents CH3 or H; and a nucleophilic initiator.
