Blue Chromating / Blue Passivation for Zinc – Corrosion Protection and Decorative FinishProtect and enhance the appearance of zinc-plated surfacesThis Blue Chromating Solution for zinc surfaces is designed for the post-treatment of electroplated zinc coatings. It helps protect zinc surfaces against premature oxidation and tarnishing while improving their decorative appearance. Depending on the immersion time, the treatment can produce a glossy, bluish-iridescent or increasingly matte finish.Blue passivation is particularly suitable for components that have been electroplated with zinc. It helps reduce the tendency of zinc surfaces to tarnish and provides a more uniform, attractive finish.Another advantage is its ability to reduce or remove slight yellowish discoloration that may occur after zinc plating due to certain brightening additives, provided the surface and process are suitable.The treatment is carried out without an external electrical current at room temperature. No electroplating power supply or additional heating is required.Key BenefitsBlue chromating and blue passivation for suitable zinc surfacesPost-treatment for electroplated zinc coatingsHelps protect against zinc oxidation and premature tarnishingCreates an attractive bluish-iridescent finishCan reduce slight yellowish discoloration after zinc platingAdjustable surface appearance through different immersion timesElectroless application without an external power supplySuitable for room-temperature processingGlossy to matte finishes, depending on treatment durationDesigned for decorative post-treatment of suitable metal surfacesApplicationsBlue chromating is primarily used for the post-treatment of electroplated zinc components, including:Screws, nuts and fastenersSteel components with electroplated zinc coatingsMetal fittings and small componentsZinc-plated parts requiring an improved decorative finishZinc-plated components with slight yellowish discoloration caused by brightening additivesChromating and passivation processes are also used for certain aluminium surfaces. However, suitability of this specific product for aluminium must be confirmed against the manufacturer's technical specifications.Technical SpecificationsPropertySpecificationProductBlue Chromating / Blue PassivationApplicationElectroless post-treatmentpH value2–3Operating temperatureRoom temperature, approx. 20–30 °CRecommended immersion time15 seconds to 2 minutesSurface finishGlossy, bluish-iridescent to matteMain applicationPost-treatment of electroplated zinc componentsSurface Finish Depending on Immersion TimeThe immersion time influences both the appearance and the achievable corrosion protection. The following times are guidelines and may vary depending on the condition of the zinc coating, temperature and plating process.Immersion timeTypical effect5–15 secondsYellowish discoloration caused by brightening additives may disappear15–45 secondsGlossy, bluish-iridescent surface45–120 secondsIncreasingly matte finish; corrosion protection may increaseFor a glossier result, a shorter immersion time is recommended. If a more matte appearance is desired, the immersion time can be increased gradually.Inspect the surface regularly and adjust the treatment time to achieve the desired finish.How to Use Blue Chromating Solution1. Prepare the workpieceThe workpiece should be freshly zinc-plated, clean and free from grease, dirt and residues. Appropriate surface preparation is essential for achieving a uniform result.2. Treat the workpiece promptly after zinc platingThe blue chromating treatment should be carried out as soon as possible after zinc plating. If too much time passes, a passivation or oxide layer may form on the zinc surface, potentially interfering with or preventing uniform treatment.3. Immerse the workpiecePour the solution into a suitable, chemically resistant container. Fully immerse the zinc-plated workpiece for the desired period. The recommended immersion time is 15 seconds to 2 minutes.4. Monitor the surfaceObserve the colour development during treatment. A short immersion may reduce yellowish discoloration, while a somewhat longer treatment can produce a bluish-iridescent finish. Longer immersion times generally result in a progressively more matte appearance.5. Post-treatmentRemove the workpiece once the desired result has been achieved and continue with the post-treatment specified by the manufacturer. In particular, follow the manufacturer's instructions regarding rinsing and drying.Important: The Zinc Coating Is Partially AttackedBlue chromating partially removes the existing zinc coating. According to the supplied product information, the zinc loss may reach up to 2 µm after an immersion time of four minutes.Avoid excessive treatment times, particularly when working with thin zinc coatings or components with tight dimensional tolerances. Follow the recommended treatment times and inspect the surface regularly.The achievable protective effect depends on the quality and thickness of the original zinc coating, surface preparation and actual process conditions. Blue chromating cannot reliably remove existing oxidation or corrosion damage.Electroless Processing at Room TemperatureThe treatment requires no external electrical current. At an operating temperature of approximately 20–30 °C, additional heating is normally unnecessary. This makes the process straightforward and convenient, particularly for post-treating small and medium-sized zinc-plated components.Blue Chromating / Blue Passivation from Betzmann GalvanikGive electroplated zinc components an attractive finish while helping protect the zinc surface against premature tarnishing. By adjusting the immersion time, the surface appearance can be influenced from glossy and bluish-iridescent to matte.Betzmann Galvanik – products for electroplating, post-treatment and professional surface finishing.

Tin‑Zinc 70/30 Electrolyte BMG‑100 Eco‑Friendly Tin‑Zinc Alloy Plating Solution for Durable Metal Coatings Short Description The Tin‑Zinc 70/30 Electrolyte BMG‑100 is a specialized electroplating solution designed to deposit a tin‑zinc alloy layer with approximately 70 % tin and 30 % zinc. This alloy coating offers excellent corrosion resistance, solderability, and ductility, while serving as an environmentally friendlier alternative to cadmium plating.  Applications This tin‑zinc alloy electrolyte is suitable for: Alloy plating with tin and zinc for protective and functional layers Corrosion protection on ferrous and non‑ferrous metals Base coatings or primers before further plating steps Functional plating for joint and mechanical components Applications that require good solderability and flexibility How It Works (Simple Explanation) Tin–zinc electroplating uses an electrical current to reduce tin and zinc ions from the electrolyte onto the surface of the part being plated. The deposited alloy forms a uniform, adherent coating that combines the beneficial properties of both metals.
