Giganet Loctite 638 (Retaining compound) –Adhesive

Part Number:



Giganet Loctita 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.
