    3M™ Scotch-Weld™ Composite Surfacing Film AF 325 LS White is a thermosetting epoxy that we developed as an excellent product for surfacing composites, where its smooth, void-free surface with minimal pinholes reduces the need for subsequent surface fill or finishing and pre-paint prep. It includes copper mesh for lightning strike protection.

    It's All About the Surface
    3M™ Scotch-Weld™ Composite Surfacing Film AF 325 LS White is a low density film that provides excellent temperature range performance from -67°F (-55°C) to 300°F (149°C) for applications required in the aerospace industry. This surfacing film is available in both white and blue, which provides color contrast to underlying composite prepreg. AF 325 LS White is co-cure compatible with most epoxy composite prepreg systems at both 250°F (121°C) and 350°F (177°C). For surfacing applications, AF 325 LS White provides a smooth surface with minimal pinholes and other surface imperfections, which reduces the need for subsequent surface filling, fairing and sanding operations. Its low density formulation aids in pre-paint surface preparation.
