Loctite® 640 is a green, anaerobic, low viscosity, methacrylate ester based retaining compound ideal for parts requiring a longer positioning time. Fixturing time on steel is 2 hr. Also used for active metals such as brass. This is a high strength product with good temperature resistance. Max diametrical clearance is 0.1 mm and service temperature is -55 to 175 deg C. Fluorescence allows product presence to be monitored.
Applications: For cylinder sleeves, valve guides, valve seats, bearings and bushings, woodruff keys, liner assemblies
