As a two-part, chemically activated adhesive system, the combination including: an adhesive formulation that is polymerizable under both aerobic and anaerobic conditions, comprising at least one polymerizable acrylate monomer, at least one elastomeric domain-providing filler, about 0.5 to 5.0 percent by weight of an organic acid that is capable of cyclic tautomerism, and a perester catalyst in an amount sufficient, when activated, to effectively initiate polymerization of said monomer; and a chemical activator formulation comprising an aldehyde/amine condensation product capable of activating said perester catalyst to initiate polymeriztaion of said monomer, and 0.001 to 0.5 percent, based upon the weight of said activator formulation, of a metal accelerator selected from the group consisting of ferric ion, cupric ion and ferrous ion.
