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—Rwherein X is a linear or branched alkylene radical optionally interrupted with one or several oxygen atom(s), and Ris 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 —O(CHR—CHO)— where n ranges from 1 to 10 (Michael acceptor M1), and Rrepresents CHor H; and a nucleophilic initiator.

Two-part curable composition

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); —a transition metal complex; and —an antioxidant; ⋅a second part (component B) comprising: —a per-compound; —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 the composition comprises (in the first part and/or in the second part) at least one compound C comprising a radical -EWG-CH-EWG- wherein EWGand EWGare independently of each other an electron withdrawing group.
