LOCTITE 222 is a low-strength anaerobic adhesive designed for the locking and sealing of threaded fasteners which require easy disassembly with standard hand tools. This formulation prevents loosening and leakage from shock and vibration. Consequently, it ensures reliable performance in critical applications.
General Information of LOCTITE 222
LOCTITE 222 is an acrylic-based, dimethacrylate ester. It presents as a distinctive purple liquid in its uncured state. Furthermore, it exhibits positive fluorescence under UV light, aiding inspection. This product cures anaerobically, meaning it hardens in the absence of air when confined between close-fitting metal surfaces. Its thixotropic nature significantly reduces liquid migration after application, ensuring precise placement.
This one-component system requires no mixing, simplifying industrial processes. It is particularly suitable for applications demanding easy disassembly without shearing the screw. Moreover, its low strength rating makes it ideal for fasteners requiring frequent adjustment or maintenance.
Key Features & Technical Benefits
- Low Strength: Facilitates easy disassembly using standard hand tools.
- Anaerobic Cure: Hardens reliably when confined between metal surfaces, preventing loosening.
- Thixotropic Formulation: Prevents product migration post-application, ensuring precise placement.
- One-Component System: Requires no mixing, simplifying industrial application and reducing waste.
Typical Industrial Applications
This formulation is engineered for the following applications:
- Adjustment of set screws
- Small diameter fasteners
- Long engagement length fasteners
