High Strength Bonding Retainer, 638

LOCTITE® 638 is designed for the bonding of cylindrical fitting parts, particularly where bond gaps can approach 0.25 mm.

Features and Benefits
• Cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening
and leakage due to shock and vibration
• Works on both active metals and passive substrates, exhibiting robust cure performance
• Offers high-temperature performance and good oil tolerance, and tolerates minor surface contaminants

Typical Applications
• Metal work
