BZ-207 is a trivalent chromium color passivation system used on zinc coating. The coating has high corrosion resistance and does not contain organic acids. Through a simple dipping process,the product can be uniformly bright,deep color yellow thick passivation film with strong chromium bonding force.
Zn-237 is a trivalent chromium color passivation system used on the galvanized layer. The coating has high corrosion resistance and does not contain organic acids. Through a simple dipping process, the product can be uniformly bright, deep color yellow thick passivation film with strong chromium bonding force.
Galvanized trivalent chromium color zinc water BZ-208 is a kind of trivalent chromium color zinc process suitable for zinc coating. A smooth,yellowish green rainbow color passivation film is formed on the surface of the coating,and the passivation film has high corrosion resistance. This process is suitable for hanging and rolling plating.
High performance, thick film, trivalent chromium plating passivation film. The pleasing color appearance is unique among high corrosion resistance trivalent chromium passivators.
Galvanized trivalent chromium black zinc water BZ-216 is a black passivator without hexavalent chromium, suitable for hanging and rolling plating; long service life of bath liquid, easy to operate and maintain; in rolling plating or automatic line passivation, scratches of collision or friction will be repaired automatically.
contains no hexavalent chromium black passivation agent, suitable for plating and barrel plating. and sealants are used together, can produce the dense black on alkaline zinc plating passivation layer.
Black passivator without hexavalent chromium,suitable for rack plating and barrel plating. Used together with a sealer,it can produce a dense black passivation layer on the acid zinc chloride coating. When used with a sealant,the anti-white rust time of 5% salt spray test is ≧72 hours. Excellent anti-impurity performance. The bath has a long service life. Easy to operate and maintain. In barrel plating or automatic wire passivation,the scratches caused by collision or friction will be automatically repaired.
use with sealants, 5% salt fog test white rust resistance greater than or equal to 72 hours. impurity excellent performance. Plating solution has long service life. Easy to operate and maintain. in barrel plating or automatic line passivation, collision or friction scratches will automatically repair.
