3M™ Scotch-Weld™ Epoxy Adhesive DP3501 is a rigid, two-part epoxy adhesive that cures rapidly at room temperature. Delivering high shear strength, we designed this epoxy adhesive to excel in bonding metal, wood, most plastics and masonry products.
Offers High Shear Strength for Strong Bonds
Our 3M™ Scotch-Weld™ Epoxy Adhesive DP3501 is thixotropic which allows for controlled flow and easy dispensing. We engineered our adhesive to offer high viscosity for accurate positioning and application. Formulated as an easy 1:1 mix ratio, it has an approximate 8 minute work life and reaches handling strength in approximately 15-20 minutes. It is fast-curing at room temperature and reaches full cure in 48 hours. Our 3M™ Scotch-Weld™ Epoxy Adhesive DP3501 produces rigid bonds and has high shore D hardness.

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 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.
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.
