3M™ Scotch-Weld™ Epoxy Adhesive DP125 is a low odor, two-part epoxy structural adhesive that creates strong and flexible bonds on metal, ceramics and many plastics where coefficients of thermal expansion are a consideration. This versatile adhesive can be used in joining, gluing and structural bonding in appliance, general industrial, transportation and signage segments. It applies easily and flows smoothly for controlled dispensing that minimizes dripping, running and migration. The 1:1 mix ratio is ideal for bulk mixing, and with 25 minutes of work-life, there's ample opportunity to reposition. This adhesive reaches handling strength in approximately 150 minutes and is fully cured in 7 days at 72 °F (22 °C). When using this, or other Duo-Pak (DP) size adhesives, rely on 3M Applicators for convenient and accurate metering, mixing, and dispensing.

When using a Duo-Pak (DP) size adhesive, rely on 3M dispensing equipment (PDF, 1.88 Mb) for convenient and accurate metering, mixing and dispensing.

Flexible for Higher Peel Strength and Better Vibration Resistance
Our 3M™ Scotch-Weld™ Epoxy Adhesive DP125 (PDF, 28.27 Kb) is a versatile, medium viscosity, epoxy adhesive that pours easily with minimal dripping, running and migration that will flow smoothly for a 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.

Recommended Applications

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


25 Minute Work Life with Handling Strength in Approximately 150 Minutes
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).

Understanding Epoxy Adhesives
Epoxy adhesives are part of the class of adhesives called "structural adhesives," which include polyurethane, acrylic, cyanoacrylate and others. Epoxies are formulated as liquid rea¬ctive 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.

Epoxy adhesive (often referred to as epoxy glue) is widely used in building and home construction; aircraft and automobile manufacturing; bicycle, boat, golf clubs, ski and snowboard assembly as well as a host of home use and other applications. It is used virtually anywhere high-strength bonds are needed along with resistance to environmental conditions. These adhesives are popular for their ease of use, mechanical strength and chemical resistance. Formulations can be created to make epoxy for plastic flexible or epoxy for metal rigid, epoxy resin transparent or opaque, quick setting or slow setting. The versatility with which these adhesives can be formulated helps meet almost any requirement for bonding wood, metal, glass, stone and various plastics.
