Type
- LS-1000® – Is a high performance laminate applique system comprised of a 3 mil outer fluoropolymer film manufactured from ethylene-chlorotrifluoroethylene (Halar®*) and an underlying expanded copper foil sandwiched between 4-mil and 2-mil acrylic pressure sensitive adhesive designed for an easy peel-and-stick application.
- This applique product is designed to protect underlying composite surfaces from lightning with easy maintenance and repair features.
- LS 1000 has long term environmental resistance characteristics that allow it to be used in extreme outdoor environments including marine, desert and other severe locations. LS-1000® – provides excellent lightning protection to underlying substrates via a sacrificial mode that restricts most damage to the LS 1000® applique film.
- After damage LS-1000® can simply be removed and replaced to provide the same quality lightning protection that the original material provided.
- LS-1000® – is available standard with 3 mil FluoroGrip®-E, .004” expanded copper foil, and a new acrylic based pressure sensitive adhesive system developed for applications on supersonic aircraft.
- LS-1000® can also be customized to have a desired color, different gage, weight or specific metallic foil, and customized adhesive systems for applications that may require specifications outside the scope of the offered product.
Uses
- LS-1000® –applique films provides an excellent alternative to conventional embedded metallic foil composite materials used for constructing structures that are susceptible to lightning strikes. Current systems utilizing embedded metallic foils require costly maintenance and repair once the object incurs a lightning strike event.
- LS-1000® acts as a sacrificial surface layer that protects underlying composites from severe lightning strike damage and can then be easily repaired by simply removing the damaged area of the applique and replacing it with a new section. No bus bars or electrical reattachment is required.
- In addition, LS-1000® can provide desired esthetics (e.g., color), foul resistance, outstanding resistance to cleaning solvents, oils, fuels, (and other fluids or chemicals that may be systematic to the desired application), UV protection, and finally environmentally friendly corrosion and weathering protection of any underlying surface or structure.
Performance
- FluoroGrip® – LS-1000 film has outstanding resistance to chemicals, weathering and high-energy radiation.
