Blue Chromating – Blue Passivation (SW10025.1)
Chemical Passivation and Surface Finishing for Zinc-Plated Metal Parts
Short Description
The Blue Chromating / Blue Passivation SW10025.1 is a chemical solution for the non-electrolytic treatment of zinc-plated metal parts, producing a blue to dark blue protective passivation layer.
This layer provides effective corrosion protection, enhances the appearance of zinc-plated parts, and gives a professional metallic blue finish.
The treatment is simple to apply in a dip bath without electricity and is suitable as a finish after galvanic zinc plating.
Applications
Blue passivation is used for:
-
Surface finishing of zinc-plated parts
-
Aesthetic blue to dark blue coloring
-
Corrosion protection and surface stabilization
-
Finishing after galvanic zinc plating
-
Suitable for hobby, workshops, restoration, and industrial use
The color ranges from light blue to deep metallic blue, providing a high-quality visual finish.
How it Works (Simple Explanation)
-
Preparation: Ensure the metal part has a sufficient zinc layer (≥ 2 µm).
-
Dip: Immerse the zinc-plated part into the blue chromating bath.
-
Chemical Reaction: Within minutes, a blue passivation layer forms on the surface.
-
Rinse: After reaching the desired color, rinse the part with water and dry it.
The color intensity can be adjusted by varying the immersion time.
Advantages
-
Easy, non-electrolytic application – no power supply required
-
Chromium(VI)-free – safer and more environmentally friendly than traditional chromating
-
Protects zinc-plated surfaces from corrosion
-
Attractive metallic blue finish for decorative and functional applications
-
Ideal for finishing, restoration, and industrial applications
