3M Scotch-Weld Epoxy Adhesive DP420 Black, 1.25 fl oz (Pack of 1)
3M™ Scotch-Weld™ Epoxy Adhesive DP420 Black is a toughened, two-part, room-temperature curing epoxy adhesive that provides strong shear and peel strength along with a high impact and vibration resistance, making this an ideal adhesive for the most demanding end-use applications. It maintains bond strength at high and low temperatures and stands up to paint bake operations up to 400 F for 30 minutes. DP420 can be used in place of mechanical fasteners, screws, rivets, spot welds, and is excellent for indoor bonding for a variety of substrates such as metals, ceramics, wood, many plastics, ceramics, and glass. This adhesive meets the requirements for UL 94 HB. DP420 Black begins with medium viscosity for easy, controlled dispensing then dries to a black color. The mix ratio is 2:1 and provides a 20 minute work life to allow plenty of time to adjust fit prior to setting. The adhesive reaches handling strength in approximately 2hours and is fully cured in 24 hours (at 720F/220C). Both mixing nozzle and applicator are required for dispensing from the Duo-Pak cartridge and are sold separately. For best results, always use 3M™ Scotch-Weld™ EPX™ Plus II Applicator and Mixing Nozzles.
