Re: [ARSCLIST] Delamination on Aluminum base laquer disc
Please be careful when applying heat to lacquer discs. The lacquer can ignite at high temperatures. I would advise against using a heat gun.

Now for something completely different.... here's a real twist:-
Has anyone established a workable method to cause lacquer to delaminate from
the aluminum base? This would be done using a scrap lacquer disc and only for
the purpose of recovering the aluminum base cleanly and intact.
Methods like pouring boiling water on the lacquer don't work consistently... it
seems that the lacquer either sticks like glue or is easily prompted to
separate, but it isn't consistent across the surface or two sides of the the
same disc!
Possibly heat carefully applied with a heat gun?
Does anyone have any other ideas?
