Functions and Uses：
1. EB-C is alkaline copper blacken agent applicable to the plumbing fixtures and traditional hardware. It is also used for the oxidation of inner copper surface on the PCB board.
2. The produced black oxidation layer can improve the combination of the copper and the dielectric materials. EB-C also can be used for blackening the copper alloy.
Operating Components：
EB-C 180g/L
Time 2.5~3.5min
Temperature 91 ~96℃
