Trivalent Chromium Black Passivator for Zinc Plating(MX-Zn-D-31H)

Newly-designed environment-friendly zinc electroplating black passivation, no more use of metal salt, like silver, iron and nickel, as blackening compositions. No toxic metals, like silver, and hexavalent chromium in passivation solution. Easy to operate, stable solution, brightly black-colored. No use of iron salt to blackening the plating, good corrosion resistance, could reach more than 72 hours in NSS (neutral salt spray) test. Applicable to all kinds of zinc electroplating.

Potassium salt acid zinc plating brightening agent(MX-Zn-SG-01 )

MX-Zn-SG-01 can be adopted in a wide range of electrical density, good filling ability, fast plating rate, which ensures mirror effect and even, smooth plating.Soft plating, low brittleness, fine crystallization. The plating obtained are easy to be iridescently or blue-whitely passivated, then get fine passivated layers. High temperature resistance, it can be operated in a wide range of temperature

Non-cyanide alkaline zinc plating brightening agent (MX-Zn-JG-01 )

MX-Zn-JG-01 due to the iron anode, it’s no need to take the anode out during downtime. With good filling ability, the thickness variation can be controlled to the minimum limit. The distinctive physical properties allow it to be reprocessed, like, bending, rolling and clamping. Easy to manage in terms of plating solution’ composition, temperature and battery. Stable corrosion resistance can be acquired, if the passivation is carried out by passivation agent with no hexavalent chrome. Applicable to autopart.

Zinc plating trivalent chromium blue passivation(MX-Zn-D-31L)

MX-Zn-D-31L belongs to environmental protection series, high corrosion-resistant passivation, up to RoHS request, no hexavalent involved. Easy to operate, brightly and evenly colored, great brightness. Great corrosion resistance, 8μm zinc plating could reach more than 72 hours in NSS(neutral salt spray ) test. Applicable to all post-processing of zinc plating.

Zinc plating trivalent chromium color passivation(MX-Zn-D-31C)

MX-Zn-D-31C is a very cost-effective product. It belongs to environmental protection series, high corrosion-resistant passivation, up to RoHS request, no hexavalent involved. Easy to operate, brightly and evenly colored, great brightness. Great corrosion resistance, 8μm zinc plating could reach more than 96 hours in NSS(neutral salt spray ) test. Applicable to all post-processing of zinc plating.
