Henkel ECCOBOND-56C/CAT9 (50-Gram-Kit)

Additional Product Information

Overview

LOCTITE ABLESTIK 56C CAT 9 is a two-component, silver-filled electrically conductive epoxy adhesive designed for structural bonding and electrical interconnection applications. Widely used in aviation and MRO environments, it enables reliable electrical connections where hot soldering is impractical or where substrates cannot tolerate high temperatures. Maintenance teams rely on this adhesive for its low-temperature cure profile, high bond strength, low electrical resistance, and proven compliance with NASA outgassing requirements, making it suitable for sensitive aerospace assemblies.
