3M™ Scotch-Weld™ Epoxy Adhesive DP100NS is a non-sag, two-part, rigid epoxy adhesive offering a fast cure and machinability. It is a fast-setting epoxy that cures at room temperature to form a rigid bond. Its non-sag formulation ensures this adhesive stays where applied.3M Scotch-Weld Epoxy Adhesive DP100NS is a non-sag, versatile structural adhesive for general purpose bonding. It works on a variety of substrates including metals, ceramics, concrete, and wood. With a high shear strength it delivers strong, rigid performance, making it ideal for multiple applications in the electrical, general industrial, construction, and consumer goods industries. Epoxy adhesives, including 5-minute epoxy, 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.
