LOCTITE® 2620 is a red, thixotropic, medium to high strength dimethacrylate ester acrylic threadlocking paste designed for locking and sealing threaded fasteners. It cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. It is particularly suitable when extreme high temperature resistance is required.
