Product Data Sheet Revised 9/2/10
Description
L-316 is an epoxy-based surfacing film designed to be co-cured with epoxy prepregs to improve the surface of composite parts. L-316 is formulated to adapt to most epoxy systems and can be applied to the surface of fiberglass, carbon, or aramid fabrics, woven and unidirectional. L-316 is appropriate for finishing surfaces on honeycomb sandwich structures as well as on laminated or layered parts.
Advantages of L-316
  • The high strength and toughness of L-316 allows the designer to use this material in high abuse areas such as aircraft interiors, cargo systems, marine structural bulkheads, etc.
  • After cure, L-316 is paint-ready, porosity-free, and sandable (if necessary for finish).
  • L-316 may be processed in vacuum bags or autoclaves.
  • L-316 is flame retarded and capable of meeting FAR 25.853 vertical flammability requirements in panel constructions.
  • L-316 may be cured at 250°F(120°C) or 350°F(176°C) depending on performance requirements.
  • Features such as weight and support reinforcement can be modified to meet specific customer needs so that the best possible part is made.
