Anaerobic Adhesives

Typically used to augment the seal or holding force of a mechanically joined assembly, anaerobic adhesives are used as threadlockers, thread sealants, retaining materials and flange sealants. When designed into an assembly, these adhesives reduce component inventories, decrease total manufacturing costs, enhance equipment reliability, and minimize aftermarket breakdown and associated warrantee problems.

By definition, anaerobic adhesives remain liquid until isolated from oxygen in the presence of metal ions, such as iron or copper. For example, when an anaerobic adhesive is sealed between a nut and a bolt on a threaded assembly, it rapidly “cures” or hardens to form a tough cross-linked plastic with tenacious adhesion to many metals. Though anaerobic applications differ widely, in most cases the adhesive provides high shear strength.
