Light or Blue Passivation
for Zinc and Cadmium |
| Zinc Chromating Process - Blue
Pass - 2000 |
| APPLICATIONS: |
Produces a
very clear blusih bright chrome - like colour on bright zinc deposits. Minimises finger
marking and corrosion. |
| OPERATING
CONDITIONS: |
4 g/l + 12 to
15 ml/l Nitric Acid, room temperature, 5 to 30 seconds, pH 1.2 to 1.8 C.R. up to 24 hours. |
| Blue Passivation Process for Zinc -
Passval BL |
| APPLICATIONS: |
Produces a
bright, light blue iridescent - free passivated film on bright zinc deposits. Low
concentration, economical solution. |
| OPERATING
CONDITIONS: |
3 g/l + 12.5
ml/l Nitric Acid, room temperature, 10 to 20 seconds, pH 0.6 to 1.2 C.R. up to 24 hours. |
| Iridex Passivation Process -
Passival IR |
| APPLICATIONS: |
Two stage
processes minimises staining and finger marking on bright zinc deposits with only a
minimum effect on the appearance. Used without bleach stage will produced faint yellow
passivation on zinc and cadmium deposits. |
| OPERATING
CONDITIONS: |
12 g/l., Room
temperature, 5 Seconds, bleached in 50 g/l sodium carbonate solution for 15 seconds at
room temperature, C.R. up to 24 hours. C.R. without bleach 48 to 72 hours |
| Clear Passivation Process for Cadmium -
Passival CCD |
| APPLICATIONS: |
Colourless
passivation of bright or dull cadmium deposits. Gives excellent rarnish resistance and
reduces alkali staining. |
| OPERATING
CONDITIONS: |
50 g.l, room
temperature, 15 to 30 seconds. C.R. up to 24 hours. |
| Cadsal KP |
| APPLICATIONS: |
A final dip
for bright and dull cadmium deposits preventing discolouration of the plated surface.
Brightens dull deposits. |
| OPERATING
CONDITIONS: |
12 to 15 ml/l
manual operation. 10 to 20 ml/l for mechanical operation depending on dwell time, Nitric
Acid 3 to 5 ml/l, room temperature, pH 0.8 to 1.25 to 40 seconds. C.R. 100 hours minimum
C.R.with bleach up to 75 hours. |
