  • Radiation-activatable anaerobic adhesive composition
    Patent number: 4533446
    Abstract: An anaerobic adhesive composition activatable by ultraviolet or visible radiation is disclosed which forms strong bonds with lapped surfaces and which is comprised of (a) an anaerobically polymerizable acrylate ester monomer, (b) a compound which decomposes upon exposure to ultraviolet or visible light radiation to release a strong acid, (c) a peroxy free radical initiator capable of initiating the polymerization of the monomer upon substantial exclusion of oxygen and (d) an activator of anaerobic polymerization which, in the presence of a strong acid, reacts with the peroxide initiator to produce free radicals to catalyze the anaerobic polymerization of the monomer.

  • Adhesive bonding method employing two-part composition with activator enriched with dihydropyridine ingredients
    Patent number: 4450030
    Abstract: An improved two-part adhesive composition comprising as a first part monomer-in-polymer polymerizable solution and a second part, an activator enriched in its N-phenyl-3,5-diethyl-2-propyl-1,2-dihydropyridine content. The content is enriched to a concentration of at least about 70% of the second part.
