Description
Product Data Sheet
3M™ Scotch-Weld™ Metal Bonder Acrylic Adhesive DP8407NS is a high-performance, two-part acrylic structural adhesive engineered for durable metal bonding in demanding industrial applications. This toughened, non-sag adhesive delivers exceptional shear, peel, and impact strength while bonding a wide variety of metals and plastics with minimal surface preparation, including slightly oily metals.
Designed specifically for metal fabrication and industrial assembly, 3M™ DP8407NS provides outstanding durability on bare steel, aluminum, copper, brass, bronze, and galvanized steel, even in high-temperature and high-humidity environments. Its corrosion-resistant bonding performance and ability to withstand powder coat and paint bake cycles up to 400°F (204°C) for one hour make it ideal for demanding manufacturing processes.
The adhesive features a 10:1 mix ratio with approximately 4–8 minutes of work life and rapid strength build-up at room temperature, helping improve production speed and assembly efficiency. Its moderate non-sag viscosity allows for controlled application on vertical and horizontal surfaces without excessive slumping or spreading. Integrated glass beads help maintain consistent bond line thickness for reliable structural performance.
3M™ Scotch-Weld™ DP8407NS is designed to replace rivets, spot welds, screws, and other mechanical fasteners in many assemblies, helping reduce finishing work, eliminate distortion from welding, and improve overall aesthetics. The adhesive maintains excellent impact resistance and bond performance even at temperatures down to -40°F (-40°C), making it suitable for harsh service environments.
Common applications include:
- Metal fabrication and structural bonding
- HVAC equipment assembly
- Transportation and specialty vehicle manufacturing
- Appliance and industrial equipment assembly
- Signage and display fabrication
- Recreational vehicle and trailer assembly
- Replacing welds, rivets, and mechanical fasteners in metal structures
