LOCTITE 680 High-Strength Retaining Compound for Cylindrical Metal Assemblies
Product Simple Attributes
LOCTITE 680 is a green fluorescent anaerobic acrylic adhesive with medium viscosity. Key properties include one-component formulation, methacrylate ester chemistry, and high strength for cylindrical fitting parts. It cures without air in tight metal gaps and tolerates minor oil contamination.
Product Introduction
Designed to prevent loosening and leakage in high-vibration environments, LOCTITE 680 bonds active metals (e.g., mild steel) and passive substrates (e.g., stainless steel, plated surfaces). It offers oil tolerance and high-temperature resistance, enabling immediate functional use after curing. NSF 61 certified for potable water systems ≤82°C (regional approval applies).
Product Special Attributes
Unique UV fluorescence enables quality control inspection. Achieves compressive shear strength ≥24.1 N/mm² (3,500 psi) after 1 hour @93°C. Withstands intermittent temperatures up to 177°C and maintains >80% strength after 1,000 hours in motor oil, gasoline, and acids. Cold-flow properties allow sealing in gaps up to 0.15 mm.
Application Scenarios
Widely used in hydraulic pumps, gearboxes, and compressor shafts (per Henkel industrial case studies). Specific cases include:
• Automotive: Axle bearings and transmission components
• Aerospace: Landing gear fittings
• Energy: Valve seats in oil/gas systems
• Water Treatment: NSF-certified pump sleeves in potable water plants
