Key Features

• High-Strength Bond: This retaining compound provides a robust, high-strength bond for cylindrical components.
• Anaerobic Curing: The product cures in the absence of air when confined between close-fitting metal surfaces.
• Low Viscosity: Its low viscosity enables precise application, particularly in situations where a fluid adhesive is preferred.
• Oil Tolerant: Loctite 680 maintains effective bonding performance even on surfaces with minor oil contamination from industrial fluids such as cutting, lubrication, and anti-corrosion oils.
• Primerless Application: It exhibits robust curing performance on both active metals (e.g., mild steel) and passive substrates (e.g., stainless steel, plated surfaces) without requiring a primer.
• Vibration and Shock Resistance: The compound prevents loosening and leakage caused by severe shock and vibration.
• UV Fluorescent: The material is fluorescent under UV light, allowing for easy visual inspection and quality control.
• NSF/ANSI 61 Certified: This product is certified to NSF/ANSI Standard 61 for use in commercial and residential potable water systems, not exceeding 82°C (179.6°F).
• One-Part System: This is a single-component product, simplifying application.

Applications

• Cylindrical Component Assembly: Specifically designed for bonding cylindrical fitting parts.
• Bearing and Bushing Retention: Ideal for securing bearings, bushings, and sleeves into housings.
• Shaft and Gear Applications: Used for retaining gears, pulleys, and sprockets onto shafts.
• Rotor Installation: Effective for fixing rotors to electric motor shafts.
• Clearance and Interference Fits: Suitable for both slip-fitted and loose-fitting assemblies, as well as press-fit applications, accommodating diametrical gaps up to 0.015 inches (0.38 mm).
• High Dynamic Load Environments: Recommended for components subjected to high dynamic forces or cyclic loads.
• Repair and Restoration: Can be used for restoring worn parts, locking keyways, and filling voids.

Benefits

• Increased Component Reliability: Ensures 100% surface-to-surface contact, eliminating microscopic imperfections and preventing micro-movement that can lead to joint failure and fretting corrosion.
• Enhanced Performance and Durability: Delivers superior resistance to severe dynamic loads, vibration, and impact, significantly extending the service life of assembled parts.
• Streamlined Assembly Processes: Reduces the need for mechanical fasteners such as set screws, clamp rings, and snap rings, simplifying assembly procedures and potentially lowering manufacturing complexity.
• Reduced Maintenance Costs: By preventing premature wear, loosening, and leakage, the product helps minimize unexpected downtime and associated repair and inventory expenses.
• Corrosion and Leakage Prevention: Creates a reliable seal that protects against corrosion and ingress of moisture or other corrosive elements.
• Versatile Material Compatibility: Works effectively on a broad range of active and passive metals, even with minor surface contamination, offering flexibility across various industrial applications.
• Assured Quality Control: Its UV fluorescence feature allows for quick and easy visual verification of proper product application, contributing to consistent assembly quality.
