LOCTITE® 641 is a medium-strength anaerobic retaining compound designed for bonding cylindrical fitting parts, particularly where regular disassembly is required for maintenance operations. It cures when confined in the absence of air between close-fitting metal surfaces, preventing loosening and leakage due to shock and vibration. This product is ideal for applications such as retaining bearings on shafts and in housings.
- Medium Strength: Allows for ease of disassembly when maintenance is necessary.
- Ideal for Regular Servicing: Suitable for parts that require frequent dismantling, such as bearings on shafts and in housings.
- Secondary Cure with Activator: Enhances curing speed and performance when used with an activator.
Technical Specifications:
- Color: Yellow
- Fixture Time: Approximately 20 minutes
- Gap Fill: Up to 0.15 mm
- Operating Temperature Range: -55°C to 150°C (-65°F to 300°F)
- Shear Strength on Steel: 12 N/mm² (1700 psi)
- Viscosity: 600 mPa·s (cP)
LOCTITE® 641 is formulated with a blend of anaerobic acrylate compounds, providing strong adhesion to metal surfaces. Specific material composition details are proprietary and not publicly disclosed.
