LOCTITE® 232 is a brown, opaque, medium-strength, medium-viscosity anaerobic retaining compound. Specially designed for high-torque threaded assemblies and heavy press fits, it features a lubricating formulation that prevents seizing during assembly and ensures smooth disassembly even in highly stressed metal joints .
LOCTITE® 232 cures in the absence of air between tightly fitting metal surfaces, forming a robust bond that resists vibration and corrosion while easing disassembly. Its slow cure time offers extended working periods, and its lubricating properties reduce galling and thread pick-up. This makes it suitable for challenging applications such as heavy-duty press fits, highly torqued fasteners, wheels, gears, and motor shafts in industrial or automotive environments .
Colour appears brown and opaque
Viscosity is classed as medium at room temperature
Specific gravity is approximately 1.02
Fixture time is slow to allow positioning under torque
Achieves full cure within 24–72 hours depending on metal fit and environment
Designed to maintain performance up to around +300 °F (~150 °C)
Primary Chemistry: Methacrylate ester
Prevents galling and seizure of metal surfaces during assembly and disassembly Secures high-torque joints and heavy duty press fits Reduces maintenance downtime thanks to reliable yet removable bonds Eliminates the need for mechanical locking devices or pre-cut gaskets
Ideal for press fits, gear and wheel mounting, splines, shafts and other cylindrical joints subject to high torque Works effectively on steel, stainless steel, aluminium and brass Suitable for maintenance, OEM assembly, and rebuild applications in automotive, industrial machinery and power generation equipment Apply while surfaces are clean or lightly oiled and allow full cure before moving or loading parts
