It comprises 3 agents ,the first one is for bath make-up ,the second one is called additive(A) which is a light green solid mixture and the last one is additive(B),a light red transparent liquid .The color produced by this agent will be very similar to purple bronze, with the good lightfastness and weather fastness. | ||
1. Bath Composition (For make-up): | ||
SN-8 H2SO4 Deionized Water |
30 g/L 16 g/L balance |
|
2. Operational Parameters: | ||
Voltage Temperature Time |
15 V~18 V 15 ℃~25 ℃ 2 min~6 min |
