3M™ Scotch-Weld™ Epoxy Adhesive 1751 is an aluminum-filled, two-part epoxy adhesive that provides high-strength, rigid bonds to metal. This epoxy formulation is ideal for repairing holes, dents, and cracks in metal.

We formulated our 3M™ Scotch-Weld™ Epoxy Adhesive 1751 to provide rigid, high-strength bonds for metal, wood, masonry, some plastics and composites. It features high viscosity for accurate application, particularly for projects that require void-filling. Epoxy adhesives 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

  • Ideal for general industrial, sporting goods, solar energy, wind energy, composites, electronics, military, transportation, and aerospace applications
  • Designed for bonding, gluing, adhering, joining, attaching, assembling
  • Ideal for hard disk drive component assembly
