Anaerobic Adhesives

Tough, lockdown defenders against leaks and vibration loosening.

Solid protection against fluid migration

Anaerobic adhesives, sometimes called threadlockers, sealants or retaining compounds, are one-part adhesives that cure on active metal surfaces in the absence of oxygen in the bond line. The requirement for lack of oxygen means these chemistries do not bond well to glass, plastic or rubber. These products reduce maintenance and leakage to help keep factories running efficiently.

Key benefits of anaerobic adhesives

Shear Strength

Threadlockers provide strong bonds that resist both direct force and extended periods of vibration
Water Intrusion

Pipe sealants inhibit leaks by preventing fluids from migrating along threaded fittings
Noise, Vibration & Harshness

Stiff bonds resist vibration and reduce opportunities for loose parts to make unwanted noise
