Passivation for Bare Corrosion Protection on Aluminium
Bare or unpainted aluminium components require reliable protection against environmental influences in industrial applications.
Protective Coatings for Unpainted Aluminium Surfaces and Alloys
KIESOW’s passivation product PROSEAL MG 300 forms a thin, resistant protective layer on aluminium surfaces that protects the base material against oxygen corrosion without negatively affecting the dimensional accuracy or electrical conductivity of the components.

Pre-treatment Before Aluminium Passivation: Degreasing and Acid Pickling
A flawless and homogeneous passivation layer requires a perfectly prepared surface. The pre-treatment steps, consisting of degreasing and acid pickling, create a precisely defined reactive metal surface for the subsequent passivation with PROSEAL MG 300. This ensures excellent bare corrosion protection for aluminium.
KIESOW offers precisely matched degreasing and pickling products for these process steps. You can choose between powder and liquid products.
| Acid pickling products | Powder | Liquid | Description |
|---|---|---|---|
| Deoxidizer DO 40 | X | X | Powder formulation for the rapid removal of residues on aluminium surfaces after alkaline pickling processes. Can be used for deoxidation or pickling prior to passivation. |
| SURFASÄURE AL Basis | X | SURFASÄURE AL Basis is a liquid acid concentrate that, together with SURFACOTE Additive No. 6, is used as an aluminium pickling or deoxidising agent in immersion and spray processes. | |
| SURFACOTE Additiv Nr. 6 | X | It pickles or activates aluminium surfaces before passivation. |
