03Technical information

This compound is a one-part, non-curing polyester-based material supplied as a thixotropic paste, allowing controlled application using a brush or spatula. It remains permanently mastic after application, maintaining flexibility and protective performance even after prolonged exposure to aviation fuels and environmental conditions. Designed to act as a barrier against corrosion, it is particularly effective on aluminium alloys and at interfaces between dissimilar metals. Its non-hardening nature allows it to absorb vibration and movement without cracking or losing effectiveness.
