LOCTITE 648 Retaining Compound

Features and Benefits

LOCTITE 648 is a low viscosity, high strength retaining compound with high temperature resistance. Ideal for retention of parts with a clearance or interference fit.
LOCTITE® 648 is a green, fluorescent, low viscosity, high strength, urethane methacrylate acrylic, anaerobic retaining compound designed for bonding cylindrical fitting parts. It prevents loosening and leakage from shock and vibration. Typical applications include holding gears and sprockets onto gearbox shafts and rotors on electric motor shafts. It provides robust curing performance.
