LOCTITE® 549
Features and Benefits
A 1-part, orange, anaerobic-curing gasketing product ideal for sealing close-fitting metal flanges.
LOCTITE® 549 is an orange, medium strength, slow curing, thixotropic methacrylate gasketing product. It cures in the absence of air at room temperature when confined within close-fitting metal parts, to seal rigid metal faces and flanges. The viscosity is 20,000 mPas and service temperature -55°C to 150°C (-67°F to 302°F).
- Thixotropic for ease of application
- Slow-curing
- Provides instant seal to low pressures immediately after assembly
- 1-part: no mixing required
- Medium viscosity
