Permabond Anaerobic Adhesives & Sealants includes an extensive line of products used as a Threadlocker, Pipe Thread Sealant, FIP Form in Place Gasket and Retaining Compound
Anaerobic sealants will not cure without the presence of metal and lack of oxygen. As it turns out, that is exactly what happens when an anaerobic sealant (adhesive) is sealed between a nut and a bolt on a threaded metal assembly or between two closely fitted metal cylindrical parts. With active metal ions and no oxygen, anaerobic adhesives and sealants rapidly cure to form a tough cross-linked plastic that will bond quite well to many metals.
There are 4 basic types of anaerobic sealant adhesives, namely:
Retaining compound – these bond and seal cylindrical joints
Threadlocker, – which bond and seal threaded metal fasteners
Thread sealant – which bond and seal threaded pipes and fittings
FIP Form in place gasket – FIPs create a gasket directly on a part
Within each type of application products vary by strength, temperature resistance, set speed, viscosity and gap fill.
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.
