Henkel LOCTITE-4305 (20GM-BOTTLE)

Additional Product Information

Overview

LOCTITE 4305 is a high-performance cyanoacrylate adhesive with UV/visible light cure, designed for rapid fixturing of plastics, rubbers, and metals in aviation and MRO applications. Its dual-cure system ensures exposed areas cure instantly under UV light while shadowed areas cure via ambient humidity, providing reliability and speed for assembly teams. MRO teams rely on it for precision bonding, disposable medical device assembly, and situations requiring minimal surface blooming and rapid production turnaround.
