<p>A stable, anaerobically-hardening adhesive system based on polymerizable methacrylates and acrylates which are free of peroxides and hydroperoxides and harden at an accelerated rate under anaerobic conditions having, for 100 parts by weight of said polymerizable methacrylates and acrylates, from 0.2 to 10 parts by weight of at least one HN-acidic compound, from 0.2 to 5 parts by weight of at least one tertiary amine having at least one hydrocarbon aryl attached to the nitrogen, and from 0.1 to 5 parts by weight of at least one organic percarboxylic acid. Preferred among the percarboxylic acids are peracetic acid, perpropionic acid, performic acid, perbenzoic acid and chloroperbenzoic acid. The new systems further contain preferably as HN-acidic compounds, sulfonic acid hydrazides, carboxylic acid hydrazides, sulfimides, disulfonyl imides or acyl cyanamides.</p> |
