Loctite For Hydrogen Applications

Loctite 638 High Strength Adhesive is a single-component, fast, room temperature curing adhesive that provides high shear strength. Typically used to retain cylindrical components, such as bearings on shafts or in housings, Loctite 638 is also ideal for thread sealing and/or threadlocking applications that operate in high pressures and other extreme environments.

The anaerobic adhesive cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage caused by shock and vibration. It cures on most metals without an activator or primer. The product offers high-temperature performance and good oil tolerance and tolerates minor surface contaminants.

Loctite 577 Thread Sealant is used for securing and sealing pipes and fittings and other threaded metal connections. The product achieves an immediate sealing effect against low pressures in metal pipe connections. There is no creeping, shrinking or fraying. The resistance to chemical and thermal stress is excellent and the run-off of the liquid product after application is reduced.

Benefits include improved reliability due to elimination of leaks in the field and increased productivity due to ease of application and one product compatibility for all fitting types.
