LOCTITE 638 is designed for the bonding of cylindrical fitting parts, particularly where bond gaps can approach 0.25 mm. 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. It not only works on active metals but also on passive substrates, exhibiting robust cure performance. The product offers high-temperature performance and good oil tolerance, and tolerates minor surface contaminants. Your benefits ? High temperature resistance ? Tolerates minor contaminants, including industrial oils ? High strength on all metals, including passive substrates (e.g. stainless steel) ? Ideal for shafts, gears, pulleys and similar cylindrical parts Clean Up Method Remove all sources of ignition. Evacuate and ventilate spill area. dike spill to prevent entry into water system. wear full protective equipment during cleanup. Handling: Prevent contact with eyes, skin and clothing. Do not breathe vapor and mist. Wash thoroughly after handling. Keep container closed. Use only with adequate ventilation.
