LOCTITE 222 is a low-strength anaerobic threadlocker. It is specifically designed for locking and sealing threaded fasteners. This product allows for easy disassembly using standard hand tools. It prevents loosening and leakage caused by shock and vibration, ensuring long-term reliability.
General Information of LOCTITE 222
LOCTITE 222 utilizes advanced acrylic technology. Its chemical base is a dimethacrylate ester. This formulation presents as a distinctive purple liquid in its uncured state. Furthermore, it exhibits positive fluorescence under UV light, aiding in inspection processes. This product is a one-component system, eliminating the need for pre-mixing. It cures when confined between close-fitting metal surfaces in the absence of air. Consequently, it forms a robust, low-strength bond. The material’s thixotropic nature is crucial. It significantly reduces liquid product migration after application, ensuring precise placement on the substrate.
The anaerobic curing mechanism is highly effective. For applications requiring faster cure speeds or where larger gaps are present, an activator can be employed to optimize performance. This versatility makes LOCTITE 222 suitable for various industrial environments. Its low viscosity ensures excellent thread penetration, filling all voids effectively. This product maintains its integrity across a wide range of temperatures and chemical exposures, as demonstrated by rigorous testing protocols. It offers consistent performance in demanding conditions.
Key Features & Technical Benefits
- Low Strength: Facilitates easy disassembly with standard hand tools. This feature is ideal for components requiring frequent adjustment, calibration, or servicing without thread damage.
- Anaerobic Cure: Cures reliably in the absence of air between metal surfaces. This ensures a secure lock without external catalysts, simplifying application (unless accelerated).
- Thixotropic Viscosity: Prevents product migration after application. This ensures precise placement on vertical or overhead surfaces and reduces material waste.
- Vibration and Shock Resistance: Effectively prevents loosening and leakage from dynamic stresses. This significantly enhances the reliability and extends the operational lifespan of assembled components.
Typical Industrial Applications
This formulation is engineered for the following applications:
- Locking and sealing small diameter threaded fasteners, such as those found in electronics.
- Securing fasteners with long engagement lengths, where controlled disassembly is critical.
- Adjusting set screws and other calibration components without damaging the threads during removal.
