Existco Anodised Aluminium Barcodes

Existco's Anodised Aluminium Barcode Labels are Graffiti, Fade, Weather, Scratch, Solvent, Salt and Temperature resistant, Designed for extreme environments.

Anodising is the electrically induced oxidation of the surface of aluminium in an acidic solution. The anodised layer is greatly increased in thickness over that of natural oxidation.

By controlling temperature, current, voltage and concentration the thickness of the oxide coating may be accurately controlled to give a high degree of protection against the atmospheric conditions prevailing in our environment.

Colour anodised aluminium in building and architectural applications has a proven track record of resistance to outdoor exposure in excess of 50 years.

Using anodised aluminium, as the base for multi-coloured products opens up enormous possibilities for applications where paper and board are too frail and easily damaged, or where surface printing on tin, steel, plastic and conventional aluminium is subject to image erosion.

A honeycomb like structure is formed on the anodised aluminium surface. It is into a hole in the structure that the dye of the process is absorbed, causing the coating to become coloured.

The hole on is then sealed in a different acid solution. The application of controlled heat forms transparent crystals of a different form of aluminium oxide over the previously open top cell.

Dye is now trapped inside the cell, isolated from the atmosphere and therefor permanent. Dyes, not material affected by ultra violet light are used in the process. The oxide coating is very hard and corrosion resistant, perfect for a sign or similar product that requires excellent durability.

Solvent Immersion

The Image cannot be affected by solvent.
