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).
