Blue Chromate Conversion Coating – Chromium(III) Blue Passivation for Zinc & Zinc-Plated PartsProfessional Blue Passivation for Zinc – Superior Corrosion Protection with an Elegant Bluish FinishThe Blue Chromate Conversion Coating / Blue Passivation is a premium Chromium(III)-based conversion coating designed as a post-treatment for zinc and zinc-plated components. It forms a durable chemical conversion layer on the zinc surface, significantly improving corrosion resistance and extending the service life of the zinc coating.After treatment, the surface develops the characteristic light bluish tint typical of professional blue chromate conversion coatings, giving zinc-plated parts a clean, high-quality appearance while providing excellent long-term protection against corrosion.Unlike traditional blue chromate processes based on Chromium(VI), this modern formulation is based on Chromium(III) and is completely free of highly toxic Chromium(VI). It offers a safer and more environmentally friendly alternative while maintaining excellent protective properties.The product is supplied ready to use and is applied simply by immersion. No power supply, electrodes, or additional equipment are required.ApplicationsThe Blue Passivation is ideal for:Zinc-plated componentsZinc surfacesScrewsNutsWashersFastenersBracketsSheet metal partsAutomotive componentsClassic car restorationMotorcycle restorationMechanical engineering componentsIndustrial partsModel engineeringDecorative metal finishingSuitable for:Electroplating companiesMetal fabrication workshopsRestoration specialistsClassic car workshopsIndustrial usersProfessional workshopsHobby usersProduct BenefitsExcellent corrosion protectionDurable chemical conversion coatingChromium(III)-based technologyCompletely free of Chromium(VI)Easy immersion processNo power supply requiredNo electrodes requiredReady-to-use solutionCharacteristic light bluish finishExcellent underfilm corrosion resistanceIdeal as a post-treatment after zinc platingSuitable for professional and hobby applicationsHow It WorksThe Blue Passivation is applied immediately after zinc plating.Simply immerse the clean zinc-plated workpiece into the ready-to-use passivation solution.Without applying electrical current, a fine Chromium(III) conversion coating forms within a few minutes, protecting the zinc surface while producing the characteristic light bluish appearance.After treatment, rinse the workpiece thoroughly with distilled water and allow it to dry completely for maximum corrosion resistance and optimum coating performance.Application NotesDuring the conversion coating process, a small portion of the zinc surface is chemically converted. Therefore, the zinc coating should have a minimum thickness of 2 µm before passivation.The Blue Passivation is intended exclusively as a finishing treatment for zinc-plated surfaces.Suitable Base MaterialsThe Blue Passivation is suitable for:Zinc-plated steelElectroplated zinc coatingsZinc surfacesAluminium (depending on alloy and surface preparation)For best results, the workpiece should be clean, grease-free, and freshly zinc plated before treatment.Typical ApplicationsFrequently used for:Corrosion protection of screws and fastenersAutomotive restorationClassic car restorationMotorcycle restorationMechanical engineeringMetal fabricationIndustrial componentsSpare partsModel engineeringDecorative metal finishingAvailable VersionsReady-to-use Blue Chromate Conversion Coating / Blue PassivationAvailable in various container sizesQuality from Betzmann GalvanikBetzmann Galvanik supplies premium electroplating chemicals for professional surface finishing.
