Loctite 609 – High-Strength Retaining Compound

Loctite 609 is a high-strength, fast-curing retaining adhesive designed for bonding cylindrical metal parts. It provides excellent holding power, even on close-fitting assemblies, and prevents loosening caused by vibration, shock, and thermal expansion. Its low-viscosity formula allows easy application while filling gaps between metal components.

Key Features

• High Strength: Strong retention for press-fit or slip-fit components

• Fast Curing: Quick setup once confined between metal parts

• Gap Filling: Suitable for assemblies with slight clearance between parts

• Vibration & Shock Resistant: Prevents loosening in demanding conditions

• Corrosion Protection: Seals gaps to prevent rust and fretting

• Temperature Resistant: Performs reliably in a wide range of operating temperatures

Typical Applications

• Bonding bearings, bushings, sleeves, and gears

• Securing rotors, pulleys, and shafts

• Retaining parts in industrial machinery and automotive equipment

• Assemblies requiring strong, permanent fixation
