Henkel LOCTITE-AA-3526 (1-LTR-BOTTLE)

Additional Product Information

Overview

LOCTITE AA 3526 is a one-component modified acrylic adhesive designed for rapid bonding in aviation and MRO environments. It provides flexible, transparent, and durable bonds to glass, metals, and plastics. Teams rely on it for high-speed assembly, repair, and maintenance applications due to its UV/visible light cure system and secondary heat cure capability for shadowed areas.
