Loctite 577, a renowned threadlocker from Henkel, is a highly effective adhesive designed to prevent loosening and vibration in threaded assemblies. This versatile product is widely used in various industrial, automotive, and household applications, offering exceptional reliability and performance.
Loctite 577 is a medium-strength, anaerobic threadlocker that cures in the absence of air. It is formulated with methacrylate esters, which react with metal ions on the threads to form a strong, non-permanent bond. This bond prevents the screws, bolts, and nuts from loosening due to vibration, temperature changes, or external forces.
