3M™ Scotch-Weld Epoxy Adhesive DP125 is a low odour, two-part epoxy adhesive that creates strong structural and flexible bonds on metal, ceramics, wood, and many plastics. It provides the reliability and strength you need to maintain productive, cost-effective results.

Our 3M™ Scotch-Weld™ Epoxy Adhesive DP125 is a versatile, medium viscosity epoxy adhesive that pours easily with minimal dripping, running, and migration that will flow smoothly for controlled, accurate dispensing. Its flexibility makes it ideal for applications involving dissimilar surfaces, where coefficients of thermal expansion are a consideration, for example when bonding glass to metals. The 1:1 mix ratio for our 3M™ Scotch-Weld™ Epoxy Adhesive DP125 is ideal with bulk mixing and with a 25-minute work life there's some opportunity for repositioning to keep projects on track. The adhesive reaches handling strength in approximately 150 minutes and is fully cured in 7 days (at 72°F/22°C). 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

  • General attachment applications in a variety of industries
  • Replace 5-minute epoxy for improved performance and more positioning time
