Anaerobic sealants are a niche category that will not cure without the presence of metal ions and lack of oxygen. When an anaerobic sealant is placed between a nut and a bolt on a metal assembly or between two closely fitted parts, they will rapidly cure to form a tough cross-linked plastic which bonds well to many metals. These unique properties make anaerobic sealants perfect for thread locking applications.

At Ellsworth Adhesives Europe, we supply a range of anaerobic threadlocker sealants by Permabond.
