Safety Information: GORE^® SKYFLEX^® Aerospace Materials, 700 Series

Supplied as a rolled good or die-cut gasket on a carrier film, GORE SKYFLEX Aerospace Materials, 700 Series do not contain any of the REACH Regulation (EU/1907/2006) Candidate List of Substances of Very High Concern (SVHC) at concentrations above 0.1% (w/w) as published by the European Chemicals Agency (ECHA). They are described in EC Regulation 1907/2006/EC and defined as the following:

• An article in the United States per OSHA Regulation 29 CFR 1910.1200(b)(6)(v) during normal intended use
• A “manufactured item” under Canadian CEPA regulations

Further, all Gore products are pre-qualified and tested to meet the latest industry standards. As a result, a Safety Data Sheet (SDS) or Material Safety Data Sheet (MSDS) is not required for GORE SKYFLEX Aerospace Materials, 700 Series. It is important to note, however, that the carrier film should be removed at the point of use.

Made of non-hazardous substances, maintenance personnel don’t have to use personal protective equipment (PPE) when they install, remove and repair GORE SKYFLEX Aerospace Materials, 700 Series (with adhesive or no adhesive). However, hazardous decomposition byproducts may form if the materials are involved in a fire or cut/removed using burning, grinding or elevated temperature processes. These byproducts could include:

• Hydrogen
• Silicon oxides
• Formaldehyde
• Carbon dioxide
• Carbonyl fluoride
• Carbon monoxide
• Hydrogen fluoride
• Tetrafluoroethylene
• Perfluoroisobutylene
• Hexafluoropropylene
• Traces of incompletely burned carbon products

For the installation or repair of GORE SKYFLEX Aerospace Materials, 700 Series, Gore recommends the following standard practices be used to reduce exposure to decomposition byproducts:

1. Download Gore’s step-by-step instructions or how-to videos.
2. Do not heat the materials with adhesive over 120°C (248°F) or non-adhesive materials over 260°C (500°F).
   • Note: The temperature will be dependent on the specified adhesive.
3. If not using effective local exhaust ventilation and PPE, avoid doing the following to the materials:
   • Burning
   • Grinding
   • High-temperature cutting
   • Melting
4. Protect the materials from potential fire sources and remember that hydrogen fluoride fumes emitted during a fire may react with water, forming hydrofluoric acid.
5. In the event of a fire, follow these steps:
   • Use full PPE, including a self-contained breathing apparatus, to avoid developing symptoms pertaining to polymer fume fever.
   • Wear neoprene gloves when handling refuse from a fire.
6. Adhere to local, state, national and international regulations when disposing of the materials.

Tapes and gaskets from W. L. Gore & Associates are available in a variety of material sets, forms, and sizes and are often used as an alternative to Form-In-Place (FIP) seals.
