An adhesive composition comprising Components A, B and C as follows:A. a polymerizable monomeric allyl 2-cyanoacrylate containing portion comprising1. from about 75 to about 92 parts by weight of allyl 2-cyanoacrylate;2. from about 1 to about 12 parts by weight of a difunctional monomer diester of an acid from the group consisting of acrylic and methacrylic acid and an aromatic diol; and3. from about 3 to 20 parts by weight of a thickening agent selected from poly(methylacrylate-coacrylonitrile) polymers;B. from 0.1 to 3.0 weight percent based upon the weight of component A of a hydrophobic cyclic imino initiator selected from 2,4,6-tri(allyloxy)-S-triazine, tri(alkyloxy)-S-triazines having 1 to about 20 exocyclic carbon atoms, benzoxazole and substituted benzoxazoles; andC. an amount of an organic peroxide free radical providing compound sufficient to cause cross linking of the difunctional monomer diester with the allyl 2-cyanoacrylate.
