Anaerobic Adhesives

Hernon Anaerobic adhesives

Nuts N’ Bolts® 423 is a single component anaerobic thread locking material, which is thixotropic and develops medium strength bonds.

Anaerobic Adhesives That Reduce the Stress Across Entire Bonded Surfaces

Anaerobic adhesives are adhesives that cure in the absence of oxygen and in the presence of active metals. These adhesives are malleable until confined in the absence of air between close-fitting active metal surfaces. Commonly used to enhance the holding strength of threaded assemblies in the form of thread sealants and thread lockers, these adhesives can also be used as pipe sealant, retaining compounds, thread lockers, structural adhesives, Form-In-Place gasket materials and specialty applications such as ammunition sealants.
