Black passivation

Black passivation

I. Functions
1) Can improve the dispersion of alkaline cyanide-free galvanized bath and make the
thickness of high and low area coating uniform.
2) Cationic quaternary amine salt compounds containing chlorine. It has the function of
settling metal powder and is used in full synthesis formula. It can chelate the metal
powder and make it settle to the bottom of the tank liquid, keep the coolant clear,
avoid reducing the cooling performance of the system because the metal powder is
wrapped in foam, and have bactericidal function at the
same time, which is helpful to
reduce the amount of fungicides added.
II. Characteristics/ Advantages
Excellent ductility
Excellent secondary processing capacity
Excellent coverage and uniform distribution
