LOCTITE^® 672 is a yellow fluorescent, medium-strength retaining compound for bonding cylindrical fitting parts, particularly where disassembly is required for service operations. It's typically used for retention of bearings onto shafts and into housings. This low viscosity urethane methacrylate acrylic liquid cures when confined in the absence of air between close-fitting metal surfaces. It’s designed to prevent loosening and leakage from shock and vibration.
