GORE® SKYFLEX® Aerospace Materials for Sealing and Surface Protection
Gore’s dry, lightweight aircraft sealants effectively protect many surfaces, simplify installation, increase throughput, improve safety and reduce lifecycle costs.
Reliable Sealing & Surface Protection
GORE® SKYFLEX® Aerospace Materials seal panels and protect surfaces from mechanical forces and harsh contaminants that can severely damage aircraft and helicopter structures. Unlike traditional curing materials, our tapes and gaskets don’t require any cure time, which reduces installation steps and simplifies the process.
Durable & Predictable Performance
Unlike low-temperature cure materials for aircraft, GORE SKYFLEX Aerospace Materials are manufactured with unique features that make them more durable against challenging environmental factors and aircraft conditions, including:
- chemically inert, non-hazardous materials
- temperature- and corrosion-resistant materials
- dry, lightweight, highly conformable materials
- available in a variety of material sets, forms and sizes
Our SKYFLEX tapes and gaskets provide many benefits that simplify aircraft assembly, increase availability and throughput, and reduce lifecycle costs, like:
- reliable, predictable sealing and surface protection and gap-filling
- proven resistance against wide temps, corrosion, abrasion, chemicals, fuels and more
- easier, quicker installation with fewer process steps and no cure time
- less replacements, rework and lifecycle costs with reusable seals
- no operator certification, training or special material handling required
- low environmental impact and improved safety with non-hazardous materials
As one of the industry’s foremost aerospace materials suppliers, we thoroughly test GORE SKYFLEX Aerospace Materials to meet many strict requirements, like SAE AMS3255™.
They’re routinely specified by leading aircraft OEMs because of their proven reliable performance for decades in a variety of secondary structures and removable applications, like:
- access panels (wing, fuel, LE/TE & dry bay)
- floorboards & structures (cargo seal & passenger area seal)
- engine cowlings
- external fuel tank sealer
- fairings
- fuel bladder cavities
- helicopter tail boom covers
- wing D-Noses
- lighting assemblies
Our PX1 Series is specifically designed for permanent load-bearing primary structures requiring robust sealing and corrosion protection while maintaining structural integrity, like:
- fuselage joints (ribs, stringers, longitudinal/orbital joints, brackets)
- joints where fasteners provide low strain and still require a seal
Our materials are approved for use on many fixed-wing and rotary-wing aircraft by OEMs like Airbus, Boeing, Bombardier, COMAC and Embraer. They’re also qualified under Technical Order (T.O.) approvals for the F-16, F-35 and V-22, among many other aircraft, spacecraft and eVTOL programs.
