Product description

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.
