3M™ Scotch-Weld™ Epoxy Adhesive 1838 is a two-part epoxy adhesive that offers rigid bonds and high shear strength. Formulated for strength, this epoxy adhesive forms a strong bond, making it ideal for projects requiring a durable bond that can be applied to a wide variety of metals, woods, and some plastics.

3M™ Scotch-Weld Epoxy Adhesive 1838 is a controlled-flow adhesive with high viscosity which allows for easy dispensing and ensures application is precise, accurate, and reaches the desired results. Scotch-Weld™ Epoxy Adhesive 1838 provides high shear strength to deliver better dead load holding. With a 4:5 mix ratio, we formulated this particular epoxy adhesive to cure at room temperature. Upon mixing, 3M™ Scotch-Weld™ Epoxy Adhesive 1838 has a 60-minute work life and reaches handling strength in approximately 8 hours and full cure in 7 days. The extended work life provides extra time to adjust the application, position parts in order to meet the desired results. Epoxy adhesives are part of the class of adhesives called "structural adhesives," which also includes 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.
