Retaining Compound - high strength. High temperature resistance.

LOCTITE® 620 is designed for the bonding of cylindrical fitting parts. The product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration. Typical applications include locating pins in radiator assemblies, sleeves in pump housings and bearings in auto transmissions. Particularly suitable for applications where temperature resistance up to 200°C is required.
