Description
LOCTITE 680 is a high-strength, anaerobic-curing retaining compound engineered for the reliable assembly and permanent bonding of close-fitting cylindrical components where low viscosity is essential. Its formulation allows excellent penetration into tight tolerances, making it ideal for press-fit and slip-fit assemblies.
The adhesive cures in the absence of air between metal surfaces, delivering a durable bond that prevents loosening and leakage caused by shock and vibration. LOCTITE 680 provides dependable curing performance on both active metals (such as mild steel) and passive substrates (including stainless steel and plated surfaces).
Designed for real-world industrial conditions, LOCTITE 680 tolerates slightly oiled or contaminated surfaces and does not require the use of a primer or cleaner. It is widely used for securing bearings, bushings, gears, sleeves, and shafts in demanding mechanical and industrial applications.
