3M™ Scotch-Weld™ Metal Bonder Acrylic Adhesive DP8407NS is a gray structural adhesive with high overlap shear and peel strength with good impact resistance and durability. This adhesive was designed to bond permanently to bare metals with minimal surface preparation, but also bonds well to wide variety of other materials, including most plastics.
- Bonds to bare, oily metals
- Withstands powder coat and paint bake cycles up to 400°F (204°C) for at least one hour
- Offers high shear, peel and impact strength for a tough and durable bond
- Provides excellent bond strength; maintains high shear strength down to -40°F (-40°C)
- 6 minute work life and fast strength build-up at room temperature
- Ideal for industrial applications with minimal surface preparation, such as slightly oily metal bonding
- Moderate non-sag formula won't slump or spread excessively
- Long shelf life, no refrigeration
What is 3M Scotch-Weld Metal Bonder Acrylic Adhesive DP8407NS used for?
3M™ Scotch-Weld™ Metal Bonder Acrylic Adhesive DP8407NS, Gray, 45 mL Duo-Pak, 12/case offers a fast and effective way to bond aluminum and other non-ferrous metals without the need for primers or surface preparation.
Can I use this adhesive on oily surfaces?
Yes! This product is designed to perform well even in high-stress environments with oily metal surfaces.
How long does it take for the adhesive to set completely?
The cure time varies depending on factors such as temperature and humidity but you can expect full handling strength within an hour and a half at normal room temperature (25°C/77°F).
When using a Duo-Pak (DP) size adhesive, rely on 3M dispensing equipment for convenient and accurate metering, mixing and dispensing.
3M™ Scotch-Weld™ Metal Bonder Acrylic Adhesive DP8407NS bonds to a variety of materials, especially bare metals such as aluminum, cold rolled steel, copper, brass, and bronze while resisting corrosion. This gray structural adhesive can even bond slightly oily metal with minimal to no surface preparation. It provides excellent bond strength and impact resistance, even at temperatures down to -40ºF (-40ºC). This adhesive is ideal for industrial applications where permanent, high-strength bonds are required. Using this adhesive helps eliminate the grinding process and surface finishing time associated with welding, spot welding, and mechanical fasteners.Recommended Applications:
- Metal office furniture
- HVAC equipment
- Specialty vehicles (ambulance, trailer, fire truck)
- Recreational vehicles (snowmobiles and ATV's)
- Metal fabrication
3M™ Scotch-Weld™ Metal Bonder Acrylic Adhesive DP8407NS Gray has been recognized by Underwriters Laboratories (UL) for use in electrical equipment and electric signs. Please review UL File QOQW2. MH17478 and Sign Components Manual (SAM) File E464624 for details.
3M™ Scotch-Weld™ Metal Bonder Acrylic Adhesive DP8407NS Gray should yield similar results as 3M™ Scotch-Weld™ Acrylic Adhesive DP8410NS Green, which has been tested for surface flammability, smoke, toxic gas generation, and caloric content per ASTM E162, ASTM E662, ASTM E1354, Bombardier SMP 800-C, and Boeing BSS 7239 test methods.
Assemblies requiring powder coating or painting typically encounter extreme temperature challenges. 3M™ Scotch-Weld™ Metal Bonder Acrylic Adhesive DP8407NS is designed to withstand powder coat and paint bake cycles up to 400ºF (204ºC) for at least one hour.
3M™ Scotch-Weld™ Metal Bonder Acrylic Adhesive DP8407NS offers a non-sag, moderate viscosity formula that won't slump or sag excessively when applied, allowing for precise application while ensuring your adhesive remains directly where you apply it, even on vertical surfaces. It starts with medium viscosity for controlled dispensing and spreads to sufficiently wet out the surface. The mix ratio is 10:1 and provides a 6-minute work life and fast strength build-up at room temperature. It offers a long shelf life, with no refrigeration necessary.
Acrylic adhesives are two-part structural adhesives that provide excellent bond strength and durability. They have several features that make them easier to use, including a much faster cure speed, higher tolerance for oily or unprepared bonding surfaces, and the ability to bond a wide variety of materials, including nearly all plastics. Newer acrylic adhesive formulations are room temperature stable with a long shelf life.
