3M™ is the industry leader in small-volume Duo-Pak adhesives, offering a huge number of choices from general purpose to extremely specialized.
Here, we offer a representative selection to illustrate the wide range of strengths, flexibilities, work times, handling times, viscosities, working temperatures, substrate types, and other properties which are available.

If you don't find an adhesive in our selection to suit your requirements, please inquire at 1-800-426-6930, as many more formulations are available. Ask for 3M Customer Service.

Duo-Pak Epoxy (100, 200, & 400 series), Urethane (600 series), and Acrylic (800 series) structural adhesives offer an alternative to mechanical fasteners and welds in metals, plastics, and wood.
They allow for greater design latitude, cleaner lines, material substitutions, less machining, lighter weight, and increased durability — often at a lower cost.
As a rule of thumb, 3M™ Structural Strength Adhesives bond the load-bearing parts of a product with a minimum of 1,000 psi overlap shear strength.

Duo-Pak adhesives are available in formulations for bonding steel, copper, aluminum, low surface energy (difficult to adhere) plastics, rubber, ceramics, composites, glass, wood, masonry, and more.
They can be used to assemble plastic structures, bicycle frames and automotive components, bond golf club heads to shafts, bond and seal radiator coils, assemble furniture and appliances, bond steel to concrete, etc., etc.

Duo-Pak cartridges are designed for use with specific applicator guns.
The majority use the 3M EPX™ Plus II Applicator gun; see the Specification Table, as well as Related Products, below.
