3M™ Scotch-Weld™ Epoxy Adhesive 1386 is a one-part, thermosetting liquid adhesive that provides exceptionally high strength at service temperatures from -70°F to 250°F (-57ºC to 121ºC). This cream coloured adhesive can be applied by knife coating, trowel, roller coating, pump, and high pressure injection methods.

Our 3M™ Scotch-Weld™ Epoxy Adhesive 1386 offers exceptionally high performance at service temperatures ranging from -70°F to 300°F (-57°C to 149°C). Suggested cure profile: 60 minutes at 350°F (177°C). Impact, fatigue, and peel performance is better than many epoxy adhesives. Our strong, reliable formula enables curing with only pressures sufficient to ensure contact between mating surfaces required. This cream coloured adhesive is a versatile product that can be applied by knife coating, trowel, roller coating, pump, and high pressure injection. 3M™ Scotch-Weld™ Epoxy Adhesive 1386 provides excellent strength after aging in typical environments. Epoxy adhesives are part of the class of adhesives called "structural adhesives" which also includes 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

  • Ideal for assembly, assembling joining, attaching, securing, repairing, panel bonding, adhering, and structural bonding applications
  • Metal to metal bonding
