Anaerobically-curing compositions are described comprising (A) a polymerizable monomer; (B) a halogen-containing compound as a first initiator component; (C) an amine, organic sulfimide or perfluoroalkyl sulfonanilide as a second initiator component; and (D) an inhibitor of free-radical polymerization. These compositions are particularly suitable as adhesives and may be formulated as thread- locking adhesives or may be modified by the addition of various modifying polymers to obtain desired properties such as increased viscosities or pressure-sensitive properties. Since the compositions of the present invention contain no peroxides or hydroperoxides, they may be stored for extended periods of time without the fear of initiator decomposition and may be manufactured without possibility of explosion.
