Composite surfacing films


Today's composites need protection from lightning strike and UV rays, as well as paint stripping processes. TenCate's composite surfacing films are designed to protect the composite while providing an aerodynamically smooth layer that facilitates paint & primer adhesion. TenCate's line of TC235 composite surfacing films can be offered with lightning strike foils for various levels of Zone 1-3 lightning strike protection. Typical film weights are 0.030 to 0.035 psf (150 to 170 gsm) and in widths of 36 inches up to 50 inches (90-127 cm). Other weights and widths are available upon request.
  • Excellent paint adhesion
  • Composite surface protection
  • Solvent resistant and durable
  • Curable under autoclave or vacuum pressure

Featured product

TC235SF-1 is a composite surfacing film designed to provide paintable composite surfaces off of the tool. TC235SF-1 may be cured under vacuum only pressure or under low autoclave pressure. The surfacing properties of TC235SF-1 allow smooth, paintable surfaces, even with thin-skinned honeycomb stiffened composite structure. TC235SF-LS is a slightly lower tack version which is combined with lighting strike foils for lightning strike protection.
