Overview

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.

3M Scotch-Weld Metal Bonder Acrylic Adhesive DP8407NS bonds to a variety of materials (especially bare metals such as aluminum, cold rolled steel, galvanized 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 -40F (-40C). 3M Scotch-Weld Metal Bonder Acrylic Adhesive DP8407NS is ideal for industrial applications where permanent, high-strength bonds are required. Using the adhesive helps eliminate the grinding process and surface finishing time associated with welding, spot welding and mechanical fasteners.
