3M™ Scotch-Weld™ Epoxy Adhesive DP490 is a non-sag, thixotropic, two-part adhesive designed for high-strength applications. This formula delivers maxiumum performance, offering outstanding heat and environmental resistance in temperatures up to 248 ºF (120 ºC). Additionally, its excellent shear and peel strength, along with its good impact durability, makes it ideal for demmanding applications like rail and automotive.
Offers Outstanding Strength and Temperature Resistance
3M™ Scotch-Weld™ Epoxy Adhesive DP490 exhibits outstanding temperature resistance up to 248ºF/120ºC, excellent shear and peel strength and good impact durability. It bonds to many difficult surfaces, including most plastics and powder coated metals. When it comes to preparation and application, 3M™ Scotch-Weld™ Epoxy Adhesive DP490 is straightforward and easy to use. Simply mix the components with a 2:1 by volume mix ratio and then apply according to the instructions to achieve a strong, long-lasting bond. The components are easy to mix and the 90-minute work life means users have ample time to re-position the bonding surfaces before a durable, long-lasting bond is achieved.
Recommended Applications
- Transportation applications, such as rail and automotive
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.
