    Details

    3M™ Scotch-Weld™ Epoxy Adhesive DP490 is a black, non-sag, thixotropic, two-part epoxy adhesive designed for high strength applications. It features a 90-minute work life and excellent heat and environmental resistance in temperatures up to 248ºF/120ºC.

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

    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
