AF 325M .035WT 3M Structural Adhesive Film 36 in x 36 yd (914 mm x 32 m)

3M™ Scotch-Weld™ Composite Surfacing Film AF 325 M, Blue 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’s About the Surface 3M™ Scotch-Weld™ Composite Surfacing Film AF 325 M, Blue 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 M, Blue 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 M, Blue 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.
