Anaerobic adhesives work by completely filling gaps between metal components. Using an anaerobic adhesive prevents loosening from vibration and also protects the joint from corrosion or rust that can result from moisture. They are typically used to augment the seal or holding force of a mechanically joined assembly. Loctite® Anaerobic Adhesives include threadlockers, thread sealants, retaining materials, and gasket sealants.

How Loctite® Anaerobic Adhesives Work
Anaerobic adhesives remain liquid until isolated from oxygen in the presence of metal ions. Though anaerobic applications differ widely, in most cases the adhesive provides high shear strength and temperature resistance. Anaerobic adhesives fixture in minutes at room temperature and fully cure within 24 hours. Full cure of anaerobics may be achieved more rapidly using short-term exposure to heat (e.g. 30 minutes at 120°C).
