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.

Testing should be carried out prior to contact with styrene, acrylic and polycarbonate based plastics to ensure compatibility.

The Loctite yellow medium strength, 50ml retaining compound liquid is designed to bond cylindrical fitting parts, particularly where disassembly is required for servicing operations. This product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration. The liquid is composed of methacrylate and provides robust curing performance. It is ideal for parts that need subsequent dismantling. It increases the reliability of slip-fitted and light press-fit parts preventing fretting, corrosion between bearing surfaces and seals against leakage.
