Fertenol is intended for use as a high-grade pickling and derusting agent for metal surfaces (iron, steel). When used for this purpose, Fertenol reliably removes rust, mill scale, scale layers, metallic dusts (e.g. after polishing) and even stubborn dirt deposits. Fertenol contains a mix of effective acid inhibitors that protect bare metal against attack. This means that the action of Fertenol on the metal is very gentle, so it is also suitable for sensitive surfaces – in the watch industry, for instance. Fertenol contains phosphoric acid that ensures a uniform coating of iron phosphate on the surface, which gives workpieces temporary protection against corrosion. Thanks to its special formula, Fertenol also provides reliable protection against hydrogen embrittlement, especially for hardened and elastic steels. The formulation also prevents cracking and subsequent material fatigue.

Fertenol is available as a concentrate that is diluted for use, depending on the degree of contamination.

Areas of application

Primarily used in an immersion bath. In this case, use dilutions of 1:1 to 1:2 with water.
Fertenol can be used variably in the temperature range from room temperature to a maximum of 50°C.
