3M™ Scotch-Weld™ epoxy adhesive DP420NS is a black, toughened, non-sag, 2-part epoxy structural adhesive that provides good strength along with high impact and fatigue resistance to meet demanding bonding challenges. 3M™ Scotch-Weld™ epoxy adhesive DP420NS can replace mechanical fasteners, screws, rivets and spot welds in many applications. When using a Duo-Pak (DP) size adhesive, rely on 3M™ dispensing equipment for convenient and accurate metering, mixing and dispensing. Our 3M™ Scotch-Weld™ epoxy adhesive DP420NS maintains bond strength at high and low temperatures and can withstand paint bake operations up to 400 deg F for 60 min. It works well on a variety of substrates such as metals, ceramics, wood, glass, many composites and plastics and is an excellent indoor bonding agent for joining, gluing, potting, panel bonding and structural bonding. 3M™ Scotch-Weld™ epoxy adhesive DP420NS meets the requirements for UL 94 HB. 3M™ Scotch-Weld™ epoxy adhesive DP420NS reaches handling strength in approximately two hours and is fully cured in 24 hr (at 72 deg F/22 deg C.) the mix ratio is 2:1 and provides a 20 min work-life, providing time to adjust for desired fit prior to curing. This adhesive is available in a variety of package sizes and can be dispensed in several ways to meet the demands of the user and the job. 3M™ Scotch-Weld™ epoxy adhesive DP420NS is appropriate for applications that will face tough environmental challenges. Formulated to provide strong adhesion for the long-term, this resilient epoxy is another way 3M™ has applied our expertise to meet and exceed the demands of even the toughest applications. 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 work-life (open 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 ov
