Electrically Conductive Materials

GelTek Conductive Gaskets Overview

GelTek conductive gaskets provide dependable, cost-effective corrosion protection for aircraft skin and antennas—protection so good that corrosion repair costs and downtime are significantly reduced.

GelTek conductive gaskets are fabricated of a conductive metal mesh impregnated with a high-performance, nonhazardous crosslinked fluorosilicone gel sealant. The gaskets are supplied precut to fit all common antenna sizes. Extensive laboratory and flight tests have shown that conductive gel gaskets provide an effective barrier against corrosion.

The gel sealant provides excellent interfacial sealing and has been formulated to withstand aviation fuels and other liquid contamination. The metal mesh incorporated in the gaskets provides electrical bonding that dissipates static charges and lightning strikes. Gel gaskets have been flight tested in both supersonic and subsonic trials with up to 12 months between inspections.

Unlike conventional sealants, the gel gasket remains soft and pliable throughout its service life. When it’s time to remove and inspect the antenna, no special tools are required to remove the antenna or the gasket. This minimizes the risk of damaging the aircraft skin during antenna maintenance. Aircraft skin exposed to the gel sealant is easily prepared for aircraft painting with industry-standard cleaning procedures and solvents.

Application Method
Remove the release film from both sides, the precured gel gaskets are then cold applied to bare metal.  No special tools, no curing time, no special coating.
