BONDERITE S-FN 7400 is an aqueous temporary corrosion protective based on organic components.
Change of colour is caused by raw material and has no impact on performance.
Application Areas
Passivation of steel and cast iron for subsequent storage in closed warehouses. Application in immersion and spray systems, especially in the last stage of multiple zone systems.
Fields of application:
- water for leak testing hollow parts, e.g. radiators, fuel tanks, intake manifolds, cooling systems and silencers
- cooling water circuit on engine test benches
- cooling water for induction hardening
- mildly alkaline solutions as well as neutral cleaner solutions for improving the corrosion protection
- prior to painting
