Product Introduction
3M™ Scotch-Weld™ Epoxy Adhesive 1386 is a one-part, thermosetting liquid adhesive that delivers exceptionally high structural strength across a broad service temperature range of -70°F to 250°F (-57°C to 121°C). This cream-colored adhesive stands out for its superior impact, fatigue, and peel performance compared to many conventional epoxies. It offers excellent strength retention even after aging in typical environments. Designed for versatility, 3M™ 1386 can be applied using various methods, including knife coating, trowel, roller coating, pumps, and high-pressure injection, making it suitable for a wide array of high-performance industrial bonding applications.
3M™ 1386 Features
- High-Temperature Performance: Maintains exceptionally high strength at service temperatures from -70°F to 250°F (-57°C to 121°C).
- Superior Toughness: Offers higher impact, peel, and bond strength than many epoxy adhesives.
- Versatile Application: Can be applied by knife coating, trowel, roller, pump, or injection.
- Durable: Retains excellent strength after aging in typical environmental conditions.
- Flame Resistant: Passes flammability testing per UL94 HB.
- Wide Cure Window: Can be cured at temperatures from 300°F to 450°F (150°C to 232°C).
3M™ 1386 Applications
- Metal-to-Metal Bonding: Engineered for high-strength bonding of metal substrates.
- Structural Assembly: Ideal for creating strong, durable bonds in demanding industrial applications.
- High-Temperature Environments: Use where bonded assemblies will be exposed to elevated temperatures.
