3M™ Scotch-Weld™ Epoxy Adhesive DP105 is a very flexible, fast-setting, two-part epoxy adhesive that cures clear for invisible bond lines.

There's no more versatile structural epoxy than 3M™ Scotch-Weld™ Epoxy Adhesive DP105. It works on a variety of substrates including metals, ceramics, glass, wood and many plastics. Its low viscosity makes it easy to dispense and self-level; and an effective tool for filleting and potting. It features high shear strength and good peel and impact performance that, when combined with good flexibility, make it ideal for a variety of applications in the transportation, specialty vehicle, electrical, general industrial, sporting goods, construction, and consumer goods industries. Epoxy adhesives, including 5-minute epoxy, are part of the class of adhesives called "structural adhesives," which include polyurethane, acrylic, cyanoacrylate, and others. Epoxies are formulated as liquid reactive polymers that undergo a chemical reaction when mixed and then cure to form a solid plastic material. Once the two parts are mixed in their specified ratio, they begin the curing process and offer a limited working time where the adhesive can be applied and the two surfaces positioned as needed. This work life lasts anywhere from a few minutes to several hours. These structural adhesives provide high shear and peel strengths, depending on the formula, and better heat and chemical resistance than other common adhesives. In general, epoxy adhesives have the highest overall strength and offer the best performance and most resistance to high temperatures, solvents, and outdoor weathering.

Suggested Applications

  • Glass to metal bonding where it sees significant temperature changes, such as glass oven doors
  • Bonding jewelry or other items where appearance is critical
  • Bonds many plastics
  • General attachment applications in a variety of industries
  • Replace 5 minute epoxy for improved performance
