Yellow Chromating / Yellow Passivation for Zinc – Golden Finish and Corrosion ProtectionGolden Yellow Passivation for Zinc-Plated SurfacesWith Yellow Passivation from Betzmann Galvanik, you can give zinc-plated components an attractive yellow to golden-yellow finish with iridescent colour effects. This electroless immersion treatment creates a decorative passivation layer with an appearance similar to traditional yellow chromating.The solution is suitable for the post-treatment of existing zinc coatings, including electroplated zinc surfaces. It can also be used to colour previously blue-passivated zinc components yellow, such as commercially available screws and fasteners.Key BenefitsGolden-yellow finish: Achieve shades ranging from pale yellow to golden yellow.Iridescent appearance: Decorative colour effects similar to traditional yellow chromating.Corrosion protection: Helps protect zinc coatings against oxidation and white rust.For zinc-plated components: Suitable for the post-treatment of existing zinc layers.Ideal for restoration work: Suitable for screws, nuts, fasteners, fittings and technical components.Easy application: Simple immersion process without a power supply or additional electroplating equipment.Chromium(VI)-free: An alternative to traditional chromium(VI)-based yellow chromating, based on chromium(III).ApplicationsYellow Passivation is particularly suitable for:Classic car restoration and automotive applicationsScrews, nuts, washers and fastenersModel making and technical componentsElectroplated zinc surfacesDecorative metal finishing and workshop applicationsInstructions for Use1. Clean and degrease the surfaceThe zinc-plated surface must be clean and free from grease. If necessary, use a suitable electroplating degreaser. Briefly rinse the component with water afterwards.2. Immerse the componentPour the Yellow Passivation solution into a suitable container and immerse the zinc-plated component completely.3. Monitor the colour developmentThe typical immersion time is approximately 30 seconds to 5 minutes. The resulting colour depends on the condition of the zinc coating, the temperature and the immersion time. Check the component regularly and remove it from the bath once the desired colour has been achieved.4. Rinse thoroughlyRinse the treated component thoroughly with water. If required, the treatment can be repeated to intensify the colour.Technical SpecificationsPropertySpecificationProductYellow Chromating / Yellow Passivation for ZincApplication methodElectroless immersion treatmentSuitable surfacesZinc-plated componentsFinishPale yellow to golden yellow, with possible iridescent effectspH value1–2Operating temperatureRoom temperature, approx. 20–30 °CImmersion timeApprox. 30 seconds to 5 minutesPackage size1,000 mlChromium(VI)Chromium(VI)-freeImportant InformationYellow Passivation is designed to post-treat existing zinc coatings and help protect them against oxidation and white rust. It does not reliably remove existing oxidation layers, so thorough cleaning and preparation are essential.During treatment, some of the zinc coating is attacked or dissolved. The zinc layer should therefore be sufficiently thick; a minimum thickness of 2 µm is recommended as a guideline. Particular care is required when treating components with thin electroplated zinc coatings.The final colour depends on the surface condition and process parameters. Identical colour results cannot be guaranteed for every component.Safety information: The product contains 3% hydrochloric acid. It may cause skin irritation, serious eye irritation and respiratory tract irritation. Wear suitable protective gloves and safety goggles. Avoid contact with eyes, skin and clothing. Keep locked away and out of reach of children.Order Yellow Passivation for Zinc from Betzmann GalvanikGive zinc-plated components an attractive golden-yellow finish and complement the zinc coating with a passivation treatment. Ideal for workshops, classic car restoration, model making and decorative metal finishing.
