Cold Sealing Process for Anodised Aluminium

Cold sealing of anodised aluminium films is one of the latest discoveries in the field of metal

finishing. Alcoseal gives a better finish to the aluminium oxide film at a lower cost than

traditional hot sealing.

It offers the following advantages:

1. Lesser energy consumption as it operates at room temperature.

2. A better finish of aluminium as it comes out of the sealing tank with a clear hydrophobic

surface which does not need further cleaning

3. Elimination of fumes from the hot sealing bath.

4. Reduction in sealing time (about 15 minutes). 5. Practically no colour change before and after sealing, as against the hot sealing process.
