How to remove pyrolitic coating on auto glass?

Forums

I work as an engineer in the automobile industry. We have vehicles that have pyrolitic coating on the auto glass which is regarded by our transport authorities as overly reflective for safety reasons. I would appreciate any information how this pyrolitic coating could be removed without destroying the glass.

Thanking you,

This glass has been coated with a metal oxide through pyrolysis when the glass leaves the tin bath (at 650

I suggest you to contact the glass manufacturer and ask for assistance. But in my opinion it would be easier to simply replace the glass.

Dear Bruce.
You need to scrub this off with a special cerium oxide polish called Regipol 501 and a stiff nylon brush.

Where are you based - there will be a wholeseller of all the equipment you will need for this task.

Does Regipol 501 really completely remove pyrolitic coating without damaged the glass? Have you try it? Is it difficult to use?

The auto glass repair can be used on the windshield or to remove acid rain spots. [url=http://www.autoglassguru.com/providers-La%20Habra-CA.html]la habra auto glass[/url]

I worked for a glass manufacturer who makes pyrolytic coatings on glass as well as for a glass processor who soft coates the glass.

You cannot remove a pyrolic coating using any means. It is applied to glass when glass is in very hot condition. The coating virtually becomes a part of glass .

By scrubbing you can peel some - but I donot feel you can use that glass in automobiles.

In the QA of coatings on glass (Soft coating as well as pyrolitic) it goes through TABER test - which is forcefully abrading the coating on a glass which rotates at high rpm using sand particles.
Even when after minutes of abrading you can see only 50% increase in light transmittivity .
