Product Introduction
Permabond® A118 is an anaerobic adhesive designed to provide permanent locking and sealing of metal parts such as bearings, gears, and studs. It exhibits high strength, excellent durability, and resistance to vibration, fatigue, and fretting corrosion. These features allow machining tolerances to be relaxed, eliminating the need for mechanical locking devices, reducing costs.
PERMABOND® A118 Features
- Excellent chemical resistance
- Improved fatigue life
- Lower cost compared to interference fit
- Low shrinkage during cure
- WRAS listed for potable water
PERMABOND® A118 Applications
- Locking and sealing of bearings, gears, and studs
- Applications involving vibration and corrosion resistance
