Anaerobic Adhesives

Metlok offers Anaerobic Adhesives. These are stable in the presence of air and cure to a solid polymer (plastic) in the absence of air. Metals accelerate the process of curing, which is why anaerobics are predominantly used for metal bonding. Polymer chemistry permits formulation of anaerobic adhesives of various strengths and viscosities. These are extensively used for locking and sealing of threads parts of prevent self-loosening, seizure due to corrosion and leakage through the threads; co-axial bonding (retaining) of cylindrical parts such as buses, ball bearings, collars, shafts, gears, cup plugs, oil seals and knobs; sealing of flat mating surfaces, eliminations of traditional gaskets; mounting of keys in key ways to prevent wallowing and loosening; impregnating porous castings, welds and powder metal parts to prevent leakage and improve mach inability. To improve and some time make electroplating possible on porous parts. In all of the above application an anaerobic adhesives/sealant of the right strength and viscosity fills the space between the two mating parts as a liquid and then hardens/cures to a solid polymer.
