Tests for Fastness of color of anodized colored aluminium




Dear Finishing Fellow Members

I would like to know how the fastness of color (gold color dyed) of anodized colored aluminium could be tested (accelerated and long term tests). Any relation of color fastness with CASS (Copper acetic acid on eBay or Amazon [affil link] Salt Spray) test.

The anodized material is used as a component for indoor application.
Any info. would be of great help to me.
With thanks and regards.

Sir,

Clariant Chemicals, formerly Sandoz, makes most anodize dyes. They do inhouse testing there. They also have lightfastness data already available on all dyes the sell.

Do you know of any reference where I might be able to find information on Colour Fastness?
I would like to know how fast different fabrics absorb the color.
Also, which fabric holds the color in itself the longest?

I think this is the wrong website for that question, Ms. Rubinova, but we'll see. -- Ted Mooney

Have you tried the "ink eraser" test? Sometimes colors will come off after rubbing the materials with an ink eraser.

The test for light fastness is ISO 2135-1984

Sombody can help me?
