Loctite 6300 has been designed for the bonding of cylindrical fitting parts. It cures when confined, in the absence of air, between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration. It is also approved for use on bearings. Loctite 6300's key differentiator is the 'White Material Safety Data Sheet. It carries no hazard symbols, risk or safety phrases and does not contain any declarable carcinogens, mutagens or reproductive toxins.
