### 6.6 Anaerobic Adhesives

Anaerobic adhesives were made commercially viable in 1953 by a chemist in Connecticut called Professor Vernon K. Krieble; whose single component curing formula started a new era of bonding possibilities. Initially developed as threadlockers, anaerobic formulations resulted in a new era of mechanical reliability by preventing vibrational loosening of mechanical fasteners; however, new solutions and applications were developed on this technology including thread sealants, gasketing and retaining compounds and several structural bonders.
