Product Introduction
3M™ Scotch-Weld™ Epoxy Adhesive EC-2615 B/A LW is a tough, two-part, room-temperature curing epoxy adhesive designed to deliver high shear and peel strength, making it ideal for demanding aerospace applications. It maintains strong bonding performance at both low and elevated temperatures and is highly resistant to challenging environmental conditions. This adhesive features a long work life and low sag characteristics for precise, controlled applications.
Formulated with a convenient 2:1 mix ratio, this adhesive offers a 60-minute work time, allowing ample time for positioning and adjusting parts prior to setting. It cures fully within 7 hours at 72°F (22°C) and can be accelerated with heat for faster production cycles. It is available in both off-white and charcoal (dark gray) colors to suit specific project needs and can be dispensed using duo-pak cartridges with the 3M™ EPX™ Applicator System for accurate and clean application with minimal waste.
3M™ Scotch-Weld™ Epoxy Adhesive EC-2615 B/A LW bonds a variety of substrates, including metals and many plastics. It is also flexible enough to withstand vibrations, making it a versatile replacement for mechanical fasteners, screws, rivets, and spot welds in structural bonding applications.

What Are Epoxy Adhesives?
3M™ epoxy adhesives are part of the structural adhesives category, which also includes polyurethane and acrylic adhesives. These adhesives are formulated with reactive components (Base and Accelerator) that cure to form durable, strong plastic materials. 3M offers epoxy adhesives in various formats to suit different applications:
- Two-Part: Base and Accelerator stored separately, allowing for long shelf life. Available in duo-pak cartridges for the 3M™ EPX™ Applicator System or in bulk for larger operations, these adhesives are mixed at the point of use to minimize waste.
- One-Part: Pre-mixed, shipped frozen, and thawed before use, these adhesives simplify processes where immediate use is preferred without mixing.
- Adhesive Films: Pre-mixed in film form for easy placement in bond lines. These films are stored frozen and are designed for clean, efficient application with consistent bond thickness.
Once mixed or thawed, epoxy adhesives offer a limited working time to apply and position components. Work life or out time varies by formulation and can range from minutes to more than 48 hours.
Epoxy adhesives provide excellent shear and peel strength, mechanical durability, and resistance to environmental factors such as moisture, chemicals, and temperature fluctuations. They are available in formulations that vary in flexibility, transparency, curing speed, and viscosity, making them suitable for a wide range of structural bonding applications.
