LOCTITE 661 - 250ml (anaerobic, UV, high strength yellow retaining compound for cylindrical assemblies)
LOCTITE® 661
Product Description
LOCTITE® 661 is designed for the bonding of cylindrical fitting parts. The product cures when confined in the absence of air between close fitting metal surfaces or when exposed to UV light of sufficient intensity to prevent loosening and leakage from shock and vibration. LOCTITE® 661 provides robust curing performance. Typical applications include holding gears and sprockets onto gearbox shafts and rotors on electric motor shafts.
