LOCTITE® 660
Features and Benefits
This very high viscosity, high-strength retaining compound is ideal for use on badly worn seats, keys, splines, bearings or tapers without re-machining. Also suitable for retaining shims.
LOCTITE® 660 is designed for the bonding of cylindrical fitting parts, particularly where bond gaps occurs without the need for remachining. The product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration. LOCTITE 660 exhibits excellent gap cure characteristics and is also suitable for retaining shims.
- Ideal for repairing worn parts without remachining
- P1 NSF Reg. No.: 123704
- Suitable for retaining shims
- Enables re-use of worn bearing seats, keys, splines or tapers
