LOCTITE 680 RETAINER HIGH 50ML

For superior holding power and precision assembly, Loctite® 680 is the go-to high-strength retaining compound for bonding cylindrical metal components. This low-viscosity, methacrylate-based liquid adhesive is engineered to deliver maximum strength and reliability in close-fitting applications, preventing loosening and leakage caused by vibration, shock, or thermal cycling.

Loctite 680 cures anaerobically (in the absence of air) between metal surfaces to form a tough, permanent bond, offering 26 N/mm² shear strength and robust performance on both active metals (like mild steel) and passive substrates (such as stainless steel and plated surfaces). With a fixture time of just 4 minutes, it’s ideal for high-speed production or maintenance tasks that demand fast turnaround and consistent performance.

Certified to ANSI/NSF Standard 61, Loctite 680 is approved for use in commercial and residential potable water systems up to +82°C, ensuring safety and reliability in a wide range of applications. It also demonstrates excellent oil tolerance and high temperature resistance up to 180°C, making it suitable for motors, gears, bearings, and other critical components.
