Abstract
The functioning of an aircraft is dependent on numerous mechanical, hydraulic and electronic systems. Access to these systems, for example for maintenance purposes, can often only be made from the outside or inside of the aircraft by removing panels. In order to protect the systems from environmental influences such as water ingress, a reliable panel sealant is required. A sealant material has been developed which before use consists essentially of a) 30-90% by weight porous base material and b) 10-70% by weight corrosion inhibitor having the requirements that it is compatible with saud porous material and has a group which is polar in nature. Preferably the porous base material is expanded polytetrafluorethylene. Further disclosed is a method for manufacturing sealantg material with anti-corrosion properties comprising the following steps: a) a first step of manufacturing a porous base sealant material (,), b) a second step of preparing a fluid (,) of a corrosion inhibitor, c) a third step of applying said fluid to said base sealant material (,) and d) a fourth step of drying the base sealant material to form the sealant material with anti-corrosion properties.
