Information
Additional Product Information
Overview
DP8005 Black (Bulk 490 mL) is a two-part structural acrylic adhesive formulated for high-volume bonding applications. Widely used in aviation and MRO environments, it enables strong, durable bonds on low-surface-energy plastics without primers. Maintenance teams rely on it to replace mechanical fasteners or plastic welding, reducing assembly weight, stress concentrations, and repair time in both scheduled maintenance and AOG scenarios.
