PRODUCT FAQ
-
What is 3M™ Scotch-Weld™ Epoxy Adhesive DP420LH used for?
3M™ Scotch-Weld™ Epoxy Adhesive DP420LH is a high-performance, two-part epoxy adhesive that provides excellent shear and peel strength. It can be used to bond a wide variety of substrates including metals, ceramics, wood, composites and many plastics.
-
Is it easy to use?
Yes! The adhesive comes in pre-measured Duo-Pak cartridges that eliminate the need for weighing or measuring.
-
How do I apply the epoxy adhesive?
To use, simply dispense equal volumes of Parts A and B onto a clean, dry surface then mix thoroughly using either manual or pneumatic methods until uniform in color.
-
What happens after the bonding process? Will there be any issues with moisture resistance or temperature range?
Once cured at room temperature over an extended period of time at least overnight , this product offers excellent heat resistance up to 265°F (129°C), very good environmental resistance to water,gasoline,fuel,oil,lubricants amongst others.Please bear in mind its handling strength is reached within about four hours(4 -12hrs).
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 DP420LH maintains bond strength at high and low temperatures and can withstand paint bake operations up to 400°F for 60 minutes. It works well in the electronics industry on a variety of substrates such as anodized aluminum, stainless steel composites and plastics, and is an excellent indoor bonding agent for joining, gluing, potting, panel bonding, and structural bonding. It is classified as low halogen as defined by the Electrotechnical Commission (IEC) 61249-2-21 Standard.
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 DP420LH dispenses as a medium viscosity adhesive for easy, controlled application. The adhesive 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 DP420LH 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.
