Product Introduction
3M™ Scotch-Weld™ Structural Adhesive Film AF 3109-2 is a family of thermosetting modified epoxy adhesives designed for durable, high-performance bonding in aerospace applications. This film provides exceptional fracture toughness and peel strength, making it ideal for bonding metal and composite solid panels, as well as honeycomb sandwich structures. Available in various weights, carriers, and an unsupported version for reticulation, AF 3109-2 offers versatile solutions tailored to specific manufacturing needs. It cures flexibly between 225°F (107°C) and 350°F (175°C) and maintains high bond strength in service temperatures ranging from -67°F to 300°F (-55°C to 150°C), ensuring reliable performance in demanding environments.
3M™ AF 3109-2 Features:
- Flexible Curing: Offers a wide curing temperature range from 225°F (107°C) up to 350°F (175°C).
- High Performance: Delivers high fracture toughness and peel strength for robust structural bonds.
- Superior Adhesion: Exhibits excellent pre-bond humidity performance on composite substrates.
- Versatile Forms: Available in multiple weights and carriers, with an unsupported version for reticulation.
- Wide Service Temperature: Provides high bond strength from -67°F to 300°F (-55°C to 150°C).
- Primer Compatibility: Compatible with a wide range of 3M™ structural adhesive primers.
- Shop Friendly: Features excellent shop handling characteristics for ease of use.
