3M SCOTCH-WELD-DP6310NS (400ML-DUO-PAK)

Additional Product Information

Overview

3M Scotch-Weld Multi-Material & Composite Urethane Adhesive DP6310NS is a high-strength, versatile urethane adhesive used in aviation and MRO applications. It reliably bonds composites, plastics, metals, and wood, providing structural strength while accommodating differences in thermal expansion. Teams depend on DP6310NS to replace mechanical fasteners such as rivets and screws, delivering clean, fatigue-resistant bond lines for aircraft assembly, repairs, and component maintenance.
