Product Description
LOCTITE® 242 is designed for the locking and sealing of threaded fasteners which require normal disassembly with standard hand tools. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. Suitable for applications on less active substrates such as plated surfaces, where disassembly with hand tools is required for servicing. The thixotropic nature of LOCTITE® 242 reduces the migration of liquid product after application to the substrate.
LOCTITE® 242 has medium-strength, medium-viscosity, thixotropic threadlocking adhesive for metal thread sizes up to M36.
Features of LOCTITE® 242
- Medium strength
- Medium viscosity
- Fast fixture
- Thixotropic for ease of application
Applications of LOCTITE® 242
- Threadlocking
