Structural Adhesive Film

Description

Modified epoxy structural adhesive film designed for bonding solid laminates and honeycomb sandwich panels in high-performance assemblies. The film format supports controlled bondline thickness, consistent adhesion, and clean handling in production and repair environments.

Key Properties

Formulated for high fracture toughness and peel strength to maintain bond integrity under cyclic loading and mechanical stress. The material provides strong resistance to moisture exposure before and after cure, supporting durability in humid and variable service conditions. Capable of effective bonding under relatively low pressure, making it suitable for sensitive or lightweight core materials.

Applications

Used in structural panel fabrication and repair across aerospace, transportation, marine, and general industrial sectors. Suitable for honeycomb sandwich structures, composite-to-composite bonding, and metal-to-composite assemblies requiring reliable structural performance.

Handling and Processing

Supplied as a supported adhesive film to enable accurate placement and repeatable processing. Compatible with standard heat and pressure cure cycles used in composite manufacturing, including autoclave, press, and oven-assisted processes, depending on substrate and design requirements.
