- Description
- Technical specification
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 due to 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.
