Permabond® A118 is an anaerobic adhesive designed to provide permanent locking and sealing of metal parts such as bearings, gears, studs and other threaded components. It exhibits high strength, excellent durability and resistance to vibration, fatigue and fretting corrosion. These features allow machining tolerances to be relaxed, and mechanical locking devices to be eliminated, with consequent cost savings.
FEATURES AND BENEFITS
- Excellent chemical resistance
- Improved fatigue life
- Lower cost than interference fit
- Low shrinkage during cure
- WRAS listed for contact with wholesome (potable) water
