  • Highly stable anaerobic compositions
    Patent number: 4038475
    Abstract: Anaerobic compositions possessing high stability, and which are capable of extremely rapid speed of cure, are prepared by adding to a combination of a polymerizable acrylate ester monomer and a peroxy polymerization initiator therefor, a small but effective amount of a soluble metal chelating agent which does not materially affect the speed of cure of the anaerobic composition when used on metal surfaces.
