Electrocoloring
Anodizing with subsequent Electrocoloring is, and will remain, very widespread because:
- results in unalterable over time
- is practically insensitive to UV rays
- is very resistant to saltiness
- is very resistant to aggressive atmosphere
Electrocoloring has been used, for over 40 years, in the following sectors:
- architectural
- interior design
- lighting engineering
- exhibition stands
- high speed rail
- automotive
- naval
- mechanical
As for the Bronze coloring, also in this process of Electrocoloring the first treatments are the same.
That is, the creation of a layer of oxide (anodizing) of Silver color.
Subsequently, the material will be immersed in an electrolytic bath to achieve a shade that will range from the lightest, which will be steel, to burnished, up to the darkest, which will be black.
The preparation of the aluminum surface can be mechanical with the finishes:
The preparation of the aluminum surface can be chemical with the finishes:
- ARC chemical matting
- ZERO CHIMICO light matting
The processing cycle involves an initial stage of anodizing (silver color), and subsequently electrocoloring is carried out in one of the 12+1 shades:
- ACCIAIO C31
- C32
- C325
- C33
- 3A
- C335
- C34
- 4A
- 5A
- 6A
- 7A (NERO)
- C35 (NERO)
- CUSTOM COLOR
NECE offers two fixing options (hydration and pore closure):
- Hot fixing CA
the shade obtained is crystalline white and Nikel-free. - Cold fixing FR
the shade obtained is cold white (tending towards green).
Depending on the application of the anodized product, the oxide layer can be class:
- 5 μm: for interiors without frequent handling
- 10 μm: for interiors
- 15 μm: for externals
- 20 μm: for exposition to aggressive atmosphere
- 25 μm: for exposition to particularly aggressive atmosphere
In particular areas of use, Anti-scratch Treatment is added to make the surface abrasion-resistant and water-proof (to make it even easier to clean) as in the case of Aluminum Frames.
REALIZATIONS
For more information:
- The finishes are made on industrial plants and comply with European standards relating to anodic oxidation processes on aluminum profiles.
- The colors and their shades in this samples are purely indicative.
- We do not accept disputes on cut, processed and assembled materials. The customer is required to check the materials before processing.
- The customer is required to ask for confirmation on codes and colors. NECE reserves the right to vary the finishes and colors without prior notice.
- Mechanical factors, which are not completely controllable by the process and oxidation, such as the type of profile, its heat treatment, the composition of the alloy, the finish and its chemical reactivity, influence the color.
