The present invention relates to a fast and elastic adhesive. Said adhesive includes two components, one including a monomer having an alkoxyalkyl ester group, a thickener, a thixotropic agent and a stabilizing agent. In the other component, a plasticizing agent, a thixotropic agent, and an initiating agent are included. This adhesive can be used to practically instantaneously bond substrates that can move relative to one another, or which may be bent or have the ability to absorb an impact, or to seal.

Fast light curing adhesive compositions, which include cyanoacrylate or methylidene malonate monomers or mixtures thereof, and either a photoinitiator system with a combination of specific ferrocene compounds and specific acylgermane compounds or a photoinitiator system with a specific ferrocene compound substituted with acylgermane groups. The use of that light curable adhesive composition, and a package.

Disclosed herein are methods of making and using cyanoacrylate compositions comprising one or more cyanoacrylates, a high level of at least one stabilizing agent and at least one free-radical polymerization inhibitor. Methods disclosed comprise making such compositions and using such compositions, for example, for occluding conduits such as fallopian tubes.

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.sub.1-CH.sub.2-EWG.sub.2- wherein EWG.sub.2 and EWG.sub.1 are independently of each other an electron withdrawing group.
