LOCTITE 638

LOCTITE 638 is a high-strength anaerobic adhesive engineered for the permanent bonding of cylindrical metal parts such as shafts, bearings, bushings, and sleeves. It delivers exceptional performance in demanding industrial environments, especially where high loads and shock resistance are required.

This compound cures rapidly in the absence of air between closely fitted metal surfaces, forming a powerful bond that prevents loosening, leakage, and wear. LOCTITE 638 is also highly tolerant of minor surface contamination, making it ideal for maintenance and repair applications.
