USD $ 27.93 – USD $ 103.32
Loctite 638 : Retaining Compound – high strength. General purpose. Fast curing.
Loctite 640 : High strength, methacrylate ester-based retaining compound that is slow curing; ideal for large diameter components and active metals such as brass
Loctite 641 : 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
Loctite 648 : Retaining compound which is typically used for holding gears and sprockets onto gearbox shafts and rotors on electric motor shafts.
Loctite 680 : High strength, methacrylate ester acrylic liquid designed for the bonding of cylindrical fitting parts, particularly where low viscosity is required.
Loctite is an brand of adhesives, sealants, surface treatments, and other industrial chemicals that include acrylic, anaerobic, cyanoacrylate, epoxy, hot melt, silicone, urethane, and UV/light curing technologies.
Features and Benefits
| Loctite 638 |
|
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.
Volume: 50ml, 250ml |
| Loctite 640 |
|
LOCTITE® 640 is a green, anaerobic, low viscosity, methacrylate ester-based retaining compound ideal for parts requiring a longer positioning time. Fixturing time on steel is 2 h. Also used for active metals such as brass. This is a high strength product with good temperature resistance. Max. diametrical clearance is 0.1 mm and service temperature is -55 to +175ºC. Fluorescence allows product presence to be monitored.

| Loctite 641 |
|
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 648 |
|
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.

| Loctite 680 |
|
LOCTITE® 680 is a green, high strength, methacrylate ester acrylic liquid designed for the bonding of cylindrical fitting parts, particularly where low viscosity is required. The product prevents loosening and leakage from shock and vibration. It provides robust curing performance. It works on active metals (e.g. mild steel) and on passive substrates (e.g. stainless steel and plated surfaces).
