The 3M™ Thermal Bonding Film AF111 is a specialized epoxy-based thermoset film adhesive designed for structural bonding in demanding industrial applications. Its formulation is tailored for bonding metals and high-strength plastic materials, such as epoxy and phenolic, making it an essential component in aerospace, automotive, and manufacturing industries.
- Moderate Tack: Offers moderate tackiness which facilitates easy handling and placement before curing, allowing for precise alignment of materials.
- Thick Film: Features a 10 mil caliper thickness, providing robust adhesive layer that contributes to the durability and strength of the bond.
- Low-Temperature Cure: Can be cured at temperatures as low as 250 degrees Fahrenheit (121 degrees Celsius), which is relatively low for epoxy adhesives, minimizing the risk of damaging heat-sensitive substrates.
- High Metal Adhesion: Exhibits excellent shear strength (OLS) and peel adhesion for metal bonding, ensuring strong and reliable bonds in applications such as metal to metal or honeycomb sandwich structures.
- High Flow: The adhesive’s high flow properties ensure complete coverage and penetration into bonding surfaces, enhancing the adhesive effectiveness and bond integrity.
- Storage Requirements: Requires storage at low temperatures, specifically around 40 degrees Fahrenheit (4 degrees Celsius), to maintain its optimal performance and shelf life.
Usage and Maintenance: When using the 3M™ Thermal Bonding Film AF111, it is crucial to ensure that all surfaces are clean, dry, and properly prepared to achieve the best bonding results. Due to its moderate tack and high flow characteristics, appropriate application techniques should be employed to prevent misalignment or excessive flow-out during curing. Regular checks of bonded joints for structural integrity and adherence to performance specifications are recommended, especially in critical applications where bond failure could lead to significant consequences.
