Product Description
LOCTITE® 246™ 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. Particularly suitable for heavy duty applications such as bolts used in transmissions, construction equipment or railroad assemblies where resistance to heavy shock, vibration and stress level is required along with exposure to elevated temperatures. The thixotropic nature of LOCTITE® 246™ reduces the migration of liquid product after application to the substrate.
Features of LOCTITE® 246™
- Can be disassembled with ordinary hand tools for easy service and maintenance
- Resistant to heavy shock, vibration and stress levels
- Thixotropic for ease of application
- Withstands temperature exposure up to 232°C (450°F)
Applications of LOCTITE® 246™
- Threadlocking
