LOCTITE 638 is a high strength, fast curing, general purpose retaining compound.

LOCTITE® 638 is designed for the bonding of cylindrical fitting parts, particularly with narrow bond gaps approaching 0.25 mm. The product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration. It not only works on active metals but also on passive substrates, exhibiting robust cure performance. The product offers high-temperature performance and good oil tolerance, and tolerates minor surface contaminants.

• Tolerates minor contaminants, including industrial oils
• High strength on all metals, including passive substrates (e.g. stainless steel)
• High temperature resistance
• Ideal for shafts, gears, pulleys and similar cylindrical parts

LOCTITE® 641 is designed for the bonding of cylindrical fitting parts, particularly where disassembly is required for servicing operations. The product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration. Ideal for parts that need subsequent dismantling, i.e. retention of bearings on shafts and in housings.

LOCTITE® 243 is a general purpose threadlocker that provides a medium strength bond. LOCTITE 243 works on all metals, including passive substrates such as stainless steel, aluminium and plated surfaces. It is proven to be tolerant of minor contamination due to industrial oils, e.g., motor oils, corrosion prevention oils and cutting fluid.

• Prevents loosening on vibrating assemblies, e.g. pumps, gear boxes or presses
• Works on all metals, including passive substrates (e.g. stainless steel, aluminium, plated surfaces)
• Proven to tolerate minor contamination by industrial oils, e.g. engine oils, corrosion prevention oils and cutting fluids
• Permits disassembly with hand tools for servicing

LOCTITE® 609 is a green, high strength methacrylate ester acrylic retaining compound designed for the bonding of cylindrical fitting parts. The product cures in the absence of air between close fitting metal surfaces. Typical applications include rotor to shafts in fractional and subfractional horsepower motors. It locks bushings and sleeves in housings on shafts, and augments press fits.

• Low viscosity
• Augments press fits
• Prevents loosening and leakage from shock and vibration
• Tested to the lot requirements of Military Specification Mil-R-46082B

LOCTITE® 577 is designed for the locking and sealing of metal pipes and fittings as well as other threaded assemblies. The product provides an instant, low-pressure seal for metal pipes and fittings. It will not creep, shrink or shred. It has excellent chemical and thermal resistance and offers less migration of liquid product after application.

• Excellent chemical resistance
• Instant low pressure seal
• Suitable for all metals
• Medium-strength, general purpose thread sealant for sealing metal threads
• Locks connection against vibration-induced loosening and other stresses
• Easy to apply
• Cures on active and inactive metals

LOCTITE® 648 is designed for the bonding of cylindrical fitting parts. The product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration. It exhibits a robust curing performance. The product also works on passive substrates and offers high-temperature performance and good oil tolerance.

• High temperature resistance
• Proven to be tolerant of minor contamination due to industrial oils
• High strength on all metals, including passive substrates (e.g. stainless steel)
• Ideal for retention of parts with a clearance or interference fit
