It’s essential to stay on schedule and within budget to get an aircraft into operation quickly — whether new aircraft are in production or existing aircraft are in critical heavy maintenance checks.

Traditional two-component materials, like polysulfide FIP wet seals are used in the industry for sealing aircraft structures. But the process involves extra steps to prepare and mix materials, apply materials within a short window, fit and re-assemble panels, remove squeeze out, wait up to an entire day to cure, and handle and remove hazardous waste. The impact can be substantial with time-consuming and labor-intensive steps that make it difficult to meet production targets, maintenance schedules and stay on budget.

What if you could speed up the process to install sealants without any mess and get the aircraft into operation quicker?


GORE SKYFLEX Aerospace Materials are dry tapes and gaskets that are considerably easier and faster to install on aircraft structures than messy FIP wet seals. Our single-component materials eliminate process steps because there’s no mixing and masking, no curing, no re-assembling panels, no cleanup after installation, and no special handling and hazardous waste disposal. With fewer process steps that take less time using our materials, you can get aircraft into operation quicker.

GORE SKYFLEX Aerospace Materials provide operators with many benefits that simplify aircraft assembly, and increase availability and throughput, including:

  • easier and faster installation from single-component, non-curing materials
  • less replacement and re-work of seals by maintaining performance over multiple open/close cycles
  • improved sealing of irregular surfaces with highly conformable materials
  • durable protection against mechanical forces, extreme temperatures, aggressive fluids, and other environmental hazards
  • no operator certification or special handling of materials required
  • low environmental impact and improved safety with non-hazardous materials
