3M™ Scotch-Weld™ Epoxy Adhesive 105 Part A is a very flexible, fast-setting, two-part epoxy adhesive that cures clear for invisible bond lines.

When using a Duo-Pak (DP) size adhesive, rely on 3M dispensing equipment (PDF, 1.9 Mb) for convenient and accurate metering, mixing and dispensing.

Extremely Flexible Adhesive Provides a Strong, Permanent Bond
There’s no more versatile structural epoxy than 3M™ Scotch-Weld™ Epoxy Adhesive 105 Part A. It works on a variety of substrates including metals, ceramics, glass, wood and many plastics. The low viscosity makes it easy to dispense and self-level; and an effective tool for filleting and potting. It features high shear strength and good peel and impact performance that, when combined with good flexibility, make it ideal for a variety of applications in the transportation, specialty vehicle, electrical, general industrial, sporting goods, construction, and consumer goods industries.

Recommended Applications

• Glass to metal bonding where it sees significant temperature changes, such as glass oven doors
• Bonding jewelry or other items where appearance is critical
• Bonds many plastics
• General attachment applications in a variety of industries
• Replace 5 minute epoxy for improved performance

Provides Handling Strength in About 20 Minutes
The mix ratio for 3M™ Scotch-Weld™ Epoxy Adhesive DP105 is 1:1 for quick, precise dispensing, and with a 5 minute working time there’s some room for repositioning to keep projects on track. The adhesive reaches handling strength in approximately 20 minutes and is fully cured in 48 hours (at 72°F/22°C).

Understanding Epoxy Adhesives
Epoxy adhesives, including 5 minute epoxy are part of the class of adhesives called “structural adhesives,” which include 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 working 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 adhesive (often referred to as epoxy glue) is 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. It is 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 epoxy for plastic flexible or epoxy for metal rigid, epoxy resin transparent or opaque, quick setting or slow setting.
