PRODUCT FAQ

What is 3M Scotch-Weld Epoxy Adhesive DP420, Black, 200 mL Duo-Pak?

The 3M Scotch-Weld Epoxy Adhesive DP420 is a two-part epoxy adhesive that provides high strength and toughness in bonding both rigid materials such as metals, ceramics and glass as well as flexible substrates like rubber, phenolic and plastic.
Can I use this adhesive on surfaces that will be exposed to weather or marine conditions?

Yes! This epoxy adhesive has superior resistance to impact, vibration, stress cracking, corrosion and extreme temperature cycling making it suitable for harsh environments which include outdoor applications.
Does it require any special curing conditions?

No, the product cures at room temperature with no oven heat required. However the cure time can be accelerated with mild heat (60-80°C).
Is this available in other colors also?

The key property of epoxy adhesives being chemical composition rather than pigment allows it to be colored into desired shade. Hence yes! we have wide range of scotch-weld epoxy adhesives available in different colors including DP460 EG which comes in gray color.

When using a Duo-Pak (DP) size adhesive, rely on 3M dispensing equipment for convenient and accurate metering, mixing and dispensing.

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 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 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; bicycle, boat, golf clubs, ski and snowboard assembly as well as a host of home use and other applications. They are used virtually anywhere high-strength bonds are needed along with resistance to environmental conditions. These adhesives are popular for their ease of use, mechanical strength and chemical resistance. Formulations can be created to make epoxies flexible or rigid, transparent or opaque, quick setting or slow setting. The versatility with which epoxy adhesives can be formulated helps meet almost any requirement for bonding wood, metal, glass, stone and various plastics.

Industrial uses for epoxies range widely and, in addition to adhesives, include coatings and composite materials like carbon fiber and glass-reinforced composites. They are the preferred choice due to their ability to flow and conform to the work area, strong adhesion, chemical and heat resistance and exceptional mechanical and electrical insulating properties.
