1.Inertia protective layer could be formed on the
passivation surface. High corrosion-resistance and heat endurance.
The color of passivation layer won't fade.
To be able to bear salt mist more than 200 hours
2.Nice adhesive force,
self preparing function to the trivalent
chromium passivation layer could be improved,
contains no hexavalent chromium.
we are mainly engaged in the related field of metal surface treatment as plating brightener,
special plating chemicals and electroplating technology research and development.We have realized an annual output of thousands of tons of plating additives.
