Loctite 680 – Retaining Compound – 10ml

As a type of anaerobic adhesive, retaining compounds are essential for the precision assembly of press- and slip-fitted parts, as well as any component that is used within systems subject to high vibration in challenging environmental conditions. Capable of filling spaces between individual components, they cure to form a strong bond and allow for the transmission of high loads without the need for air. This means sealed components and machine designs can still achieve high strength and temperature resistance across a variety of substrates.

Used across a broad range of mechanical components, as well as for bearings, shafts, and cylinder liners, retaining compounds are most commonly found within the automotive and heavy machinery industries. However, they can also be used in any industry where metal-to-metal adhesion is required for moving parts. Additionally, retaining compounds help manufacturers to avoid unnecessary machining of a broad range of mechanical components during MRO.

There are a number of reasons electrically high strength retaining compounds might be chosen over other methods of bonding and adhesion, and the advantages are clear. In fact, any type of component that will be under stress, that has a small adhesion area, and that is found within moving machinery, can benefit from retaining compounds. Moreover, any component that is at risk of fretting leading to corrosion can benefit from these materials to reduce wear and potential failure during operation.

LOCTITE® 680 High strength, methacrylate ester acrylic liquid designed for the bonding of cylindrical fitting parts, particularly where low viscosity is required.
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).

• Low viscosity
• Provides robust curing performance
• Cures when confined in the absence of air between close fitting metal surfaces
• Offers high temperature performance and oil tolerance
• Tolerates minor surface contaminations from various oils
• Certified to ANSI/NSF Standard 61 for use in commercial and residential potable water systems not exceeding +179.6 °F (+82 °C)

FAQ
Q: If anaerobics cure in the absence of air, how come they don’t cure in the sealed bottle?
A: The anaerobic bottles are specially formulated oxygen-permeable polyethylene bottles that allow air to pass through the wall of the bottle to maintain stability of the liquid product inside the container. The bottle is also not filled to the top for stability purposes. A 10 ml bottle does indeed contain 10 ml’s of product in a larger bottle, and a 50ml bottle does indeed contain 50ml’s of product in a larger bottle.
