Permabond has designed and formulated adhesives and sealants to replace or augment mechanical joining methods of cylindrical metal joints such as keyways, interference fits, or shrink fits.

Permabond’s anaerobic retaining compounds fill voids – providing 100% surface-to-surface contact, while mechanical joining techniques provide only 20% surface-to-surface contact. The increased surface area directly relates to greater load-carrying capacity providing more than 5 times that of mechanical joining techniques. This increase in strength allows engineers to relax machine tolerances, eliminate the need for heated joining processes and provides them with a method that increases the life of the components.
