Product Introduction of 3M Scotch-Weld Epoxy Structural Adhesive DP490
3M Scotch-Weld Epoxy Structural Adhesive DP490 is a non-sag, thixotropic, two-part adhesive designed for high-strength applications. This formula delivers maximum 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 demanding applications like rail and automotive.
When using a Duo-Pak (DP) size adhesive, rely on 3M dispensing equipment for convenient and accurate metering, mixing and dispensing.
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 reposition the bonding surfaces before a durable, long-lasting bond is achieved.
