Product Introduction
3M™ Scotch-Weld™ Epoxy Adhesive 2216NS is a high-strength, non-sag, two-part epoxy adhesive renowned for its flexibility and precision application. This versatile, tan-colored adhesive creates a long-lasting bond that remains pliable, effectively withstanding expansion, contraction, and environmental aging, making it perfect for bonding dissimilar materials. It offers an exceptionally long work time of up to 120 minutes, allowing for meticulous adjustments and repositioning. While it cures at room temperature, it can also be heat-cured in just 30 minutes at 200°F (93°C). Its standout feature is its ability to maintain high bond strength in extreme temperatures, including cryogenic applications down to -423°F (-252°C), making it a reliable choice for the most challenging environments.
3M™ 2216NS Features
- Multi-Substrate Bonding: Adheres to a wide variety of substrates including aluminum, metals, wood, glass, stone, and many plastics.
- Flexible & Durable: Withstands expansion, contraction, and environmental aging for a long-lasting bond.
- Non-Sag Control: The non-sag formula allows for precise, controlled application without drips or migration.
- Extended Work Time: Provides up to 120 minutes of working time for complex assemblies and adjustments.
- Fast Heat Curing: Can be fully cured in just 30 minutes at 200°F (93°C) to accelerate production.
- Extreme Temperature Performance: Excels in cryogenic bonding, tolerating temperatures as low as -423°F (-252°C).
- High Stress Resistance: Maintains bond strength under high stress and varying environmental conditions.
