SFX740-LS incorporates an integrated copper mesh layer to provide lightning strike protection with a lightweight carrier ply for conformability, making the process of applying CuMesh simple to maintain the cosmetic and processing advantages of the range.

Developed for aerospace and advanced air mobility applications, SFX740-LS combines surfacing and lightning strike protection within a single integrated material surfacing system.

Part of SHD's SFX740 range of epoxy surfacing films delivering outstanding low-defect surface quality straight out of the mould.

Why choose this material

SFX740-LS is an easy-to-use surface film providing lightning strike protection for your application.

The SFX740 range replicates the mould details perfectly once demoulded. Tailored surface tack makes placement in the mould simple and robust, and the base-chemistry is formulated such that the three new surface films work together with all SHD’s VTC and MTC epoxy prepreg systems.

Technical Guidance Information

This material should be kept frozen at -18°C (0°F). It must be kept sealed in a polythene bag which must not be opened until fully thawed to room temperature. If the material is not fully used, then the material must be resealed in the polythene bag to prevent moisture absorption.

This material contains epoxy resin, which can cause allergic reactions with skin contact. Repeated or prolonged skin contact must be avoided. Please refer to the product Safety Data Sheet before using this material. The following precautions must be taken when using epoxy surfacing films:

Overalls must be worn
Impervious gloves must be worn
Curing schedule is meant to be as a guide only and is subject to local conditions
To avoid exotherm, particular care must be taken with thick laminates
Ramp rates must not exceed 3.0°C (5.4°F)/min during initial cure and 0.3°C (0.5°F)/min during post cure
