LOCTITE® 620 High Temperature Retaining Compound
Features and Benefits
This anaerobic-curing retaining compound is designed for bonding cylindrical fitting parts, particularly where high strength with high temperature resistance is required.
When it comes to bonding locating pins in radiator assemblies, sleeves in pump housings and bearings in auto transmissions – especially when you need high temperature resistance up to 232°C (450°F) – LOCTITE® 620 is a good choice. This high strength, anaerobic-curing retaining compound is designed for bonding cylindrical fitting parts to prevent loosening and leakage due to shock and vibration. It cures when confined in the absence of air between close-fitting metal surfaces, and can fill gaps from 0.15 mm - 0.25 mm (0.006" - 0.01").
- Ideal for shafts, gears, pulleys and similar cylindrical parts
- Operating temperature: -55°C to 230°C (-65°F to 450°F)
