Toray MicroPly™ TC235SF-1
- Chemical Family
- Epoxy & Epoxy Derivatives
Toray Toray Microply™ TC235SF-1 is a composite surfacing film designed to provide paintable composite surfaces off of the tool. It may be cured under vacuum-only pressure or under low autoclave pressure. The surfacing properties of Toray MicroPly™ TC235SF-1 allow smooth, paintable surfaces, even with thin-skinned honeycomb-stiffened composite structure. Epoxy Surfacing System 121°C–177°F (250°F–350°F).

- Lightning Strike Protection
Composite surfacing films are used to aid in the Applications of the relatively fragile copper, aluminum, and bronze foils. Foils are a common method that allow composites to achieve higher levels of surface conductivity for lightning strike protection. There are several weights of foils designed to meet Zone 1A-3 protection. Airplane lightning strike zones are defined by SAE Aerospace Recommended Practices (ARP) 5414. The most likely areas to be hit are nacelles, radomes, wing tips, elevators, vertical fins, and horizontal stablizers. Common lightning strike protection includes expanded foils, wire mesh, and embedded metallic wire.

- Product Safety and Shelf Life
Apply resin side of TC235SF-1 on tool side. Tool side should be treated prior to lay-up with a composite mold release. After cure, lightly sand (150 grit) or use a Scotch-Brite pad to remove residual release chemicals. Solvent wipe and then apply primer or paint coatings.; Out Life: 30 days out life ≤ 21°C (70°F) and ≤ 60% RH; Frozen Storage Life: 12 months at ≤-18°C (≤ 0°F); Out life is the maximum time allowed at 21°C (70°F) or below and 60% or less RH before cure, after a single frozen storage cycle in the original unopened packaging at -18°C (0°F) or below for a period not exceeding the frozen storage life noted above.
