Loctite 2760 cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. Loctite 2760 is particularly fast curing thereby reducing or eliminating the need for activators. Particularly suited for heavy duty applications such as bolts used in transmissions, construction equipment or railroad assemblies where heavy shock and stress levels are required. The thixotropic nature of Loctite 2760 reduces the migration of liquid product after application to the substrate. Loctite 2760 high strength, primerless red threadlocker is particularly fast curing, eliminating the need for priming. It develops usable strength within one hour. Particularly suitable for heavy duty applications where resistance to heavy shock, vibration and stress levels are required.
