3M™ Scotch-Weld™ Epoxy Adhesive DP420
Bonds stainless steel shaft into stainless steel club head
High Peel and Shear Strength Maintains Lasting Bond at High and Low Temperatures
3M™ Scotch-Weld™ Epoxy Adhesive DP420 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, 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 DP420 Off-White meets the requirements for UL 94 HB.

Recommended Applications
  • Small joint assembly
  • Heavy-duty mounting assembly
  • Metalworking
  • Carbon fiber epoxy bonding
20 Minute Work Life Provides Time for Positioning and Adjustment
3M™ Scotch-Weld™ Epoxy Adhesive DP420 reaches handling strength in approximately two hours and is fully cured in 24 hours (at 72°F/22°C.) The mix ratio is 2:1 and provides a 20 minute 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.

Toughened for Impact and Fatigue Resistance
3M™ Scotch-Weld™ Epoxy Adhesive DP420 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 applies their expertise to meet and exceed 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 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 overall strength and offer the best performance and most resistance to high temperatures, solvents and outdoor weathering.

Epoxy adhesives are widely used in building and home construction; aircraft and automobile manufacturing; bicycl
