How to Achieve High-Quality Champagne Colour Anodizing


Dear Sir,

I have anodizing plant in Pune, India., I do plain anodizing to Aluminium sections.

Now my customers want me to do their job in "CHAMPAGNE" bright polished colour as available in USA & this colour should remain in sunlight for many months . I have tried with local made colour chemical but the shade is dark yellow & the shade has become very dull in 3-4 days.

I have installed one tank for colour process.

Will you please inform me, what steps I should adopt to get "Champagne bright polish colour" & to stay for couple of months. Also inform if any changes or additions to be made in my plant connected to tank, rectifier etc.

Thank You, Regards,

Please excuse my informal address, however, I have a very small commercial anodising plant, and specialise in decorative and protective coatings of precision and designer componentry. I have also had requests for "champagne" coloured components, and have successfully dyed with a very dilute Clariant Yellow at about 1.5 grams per litre. This results in a very washed-out green/yellow which I suppose is supposed to be "Champagne". What a conceptual colour is that? Nonetheless the clients have accepted it.

I invite further correspondence; I think that the small operators in this field have a quality-control advantage over the larger industrial-based operations and this is the angle that I am operating on. My business is only two years old, but growing (slowly and surely).
