3M™ Scotch-Weld™ Epoxy Adhesive DP405 is a black, toughened, two-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 DP405 can replace mechanical fasteners, screws, rivets and spot welds in many applications.
High Peel and Shear Strength Maintains Lasting Bond at High and Low Temperatures
3M™ Scotch-Weld™ Epoxy Adhesive DP405 maintains bond strength at high and low temperatures and can withstand paint bake operations up to 400°F for 60 minutes. It works well on a variety of substrates such as metals, ceramics, wood, glass and many composites, and is an excellent indoor bonding agent for joining, gluing, potting, panel bonding, and structural bonding.
Recommended Applications
Small joint assembly
Heavy-duty mounting assembly
Metalworking
Carbon fiber epoxy bonding
Fast 5 Minute Work Life with Quick Cure Time
3M™ Scotch-Weld™ Epoxy Adhesive DP405 dispenses as a medium viscosity adhesive for easy, controlled application. The adhesive reaches handling strength in approximately 15 minutes and is fully cured in 24 hours (at 72°F/22°C.) The mix ratio is 2:1 and provides a 5 minute work life, providing limited 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.
Toughened for Impact and Fatigue Resistance
3M™ Scotch-Weld™ Epoxy Adhesive DP405 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 meets and exceeds the demands of even the toughest applications.
What are Epoxy Adhesives?
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
