Type of pretreatment |
Notes |
|
E0 |
Degreased and deoxidized only |
Surface preparation before anodising in which the surface is degreased and deoxidized without further pretreatment. Mechanical marks such as scoring and scratching will remain visible. Corrosion effects, which could barely be seen before treatment, can become visible after processing. |
|
E6 |
Chemically etched - satinized |
After degreasing the surface is given a satin or matt finish be treatment in special alkaline etching solutions. Mechanical surface defects are smoothed out but not entirely eliminated. Any corrosion effects on the metal surface may become visible as a result of this treatment. Mechanical pretreatment before etching can eliminate these effects, but it is preferable to handle and store the metal correctly to avoid corrosion. |
Table No 3 – recommended thickness of the anodic coating
|
Use conditions |
Minimal thickness of the coating |
|
W – very hard |
25 microns |
|
C – hard or normal |
20 microns |
|
U – moderate |
15 microns |
|
L – light |
10 microns |
|
B – very light |
5 microns |
W – very hard conditions of use; very difficult environment – strong corrosion risks: sea water, highly salted atmosphere, saline fogs, industrial pollution; e.g.: seaside areas, industrial zones, construction areas.
C – hard or normal conditions of use; the environment with quite high corrosion risks outdoors (e.g. in transportation industry or construction industry); the environment with high chemical impact indoors (e.g. food industry).
U – moderate conditions of use: moderate corrosion risks, but high abrasion risk; mainly indoor applications.
L – light conditions of use: low corrosion risks and low abrasion risks; mainly indoor applications.
B – very light conditions of use: very low corrosion risks and very light abrasion risks; indoor applications.
