Product Details
The Loctite 638 is designed for the bonding of cylindrical fitting parts, particularly where bond gaps can approach 0.25 mm and where maximum strength at room temperature is required. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. It not
only works on active metals but also on passive substrates such as stainless steel and plated surfaces.
