Parson Adhesives SONLOCK™ 3640 Retaining Compound
Categories:	Polymer; Adhesive
Material Notes:	SONLOK 3640 is a high temperature resistance; low viscosity, high strength anaerobic retaining compound for bonding rigid assemblies. This adhesive used to increase the strength of mechanical assemblies. SONLOK 3640 retaining compound is a single component anaerobic adhesive, which develops high strength rapidly when confined in the absence of air between close fitting surfaces. Meets US Military Specification R-46082B Type II. Applications: Retains bushings and sleeves in housings and on shafts. Retains bearings in place, preventing spin out. Retains rotor to shafts in fractional and sub-fractional horsepower motors. Retains keys and splines. Augments press fits. Restoring the fit to worn assemblies or out of tolerance parts.
