LOCTITE® 680
Features and Benefits
This high-strength retaining compound is ideal for slip fitted parts, and also works on inactive surfaces.
LOCTITE® 680 is a green, high strength, anaerobic-curing retaining compound for the assembly and attachment of cylindrical fitting parts, particularly where low viscosity is required. The product prevents loosening and leakage from shock and vibration, and provides robust curing performance by curing on both active metals (e.g. mild steel) and passive substrates (e.g. stainless steel and plated surfaces), as well as slightly oiled or contaminated surfaces, without the need for a primer or cleaner.
- Low viscosity
- NSF/ANSI 61 certified up to 82°C (179.6°F)
- High strength and robust curing performance on inactive surfaces without primer
- Tolerates minor surface contamination
- Fluorescent under UV for quality control
