3M Scotch-Weld DP410 Epoxy Adhesive 50 ml Black - Two-Part High Strength Structural Epoxy

The 3M Scotch-Weld DP410 is a two-part epoxy adhesive engineered for demanding structural bonding applications. Unlike standard epoxies, this formulation offers a unique combination of high overlap shear strength and excellent impact resistance, making it a preferred choice for industries ranging from aerospace to electronics. Its thixotropic, non-sag consistency ensures clean, precise application on vertical and overhead surfaces without messy drips.

Highlights

• High strength structural bonding: overlap shear strength exceeds 20 MPa on steel
• Thixotropic (non-sag) paste: ideal for vertical and overhead applications
• Excellent environmental resistance: withstands temperatures from -55°C to +150°C
• Good impact resistance and peel strength for durable, long-lasting bonds
• 50 ml cartridge size with 2:1 mix ratio by volume
• Black colour for a professional finish

In daily use

This adhesive is perfect for bonding metals, composites, plastics, and ceramics where high strength and reliability are critical. The 90-minute work life gives you ample time to position parts, while handling strength is reached in 4-6 hours, allowing for efficient assembly. Full cure occurs within 24-48 hours, after which the bond achieves maximum strength. The non-sag property simplifies application on vertical surfaces, and the black colour blends seamlessly with many substrates, making it ideal for visible joints.
