Hi Vinylguru, My formula was obtained from a chemical analysis of many brands of 1940s-50s lacquer recording blanks commissioned by Library of Congress I believe (?) to study chemical breakdown of rare field recordings, and how to preserve them. It found the predominant ingredients were...

Yes, what Compositepro said... But thanks Patprimmer and Demon3, I'm also interested in all kinds of electroplating, and the info you mentioned may come in useful. I'm contemplating a career change from software engineering to mech e., with a special interest in designing, or at least planning...

Ooh yeah, expansion/contraction would make the lacquer grooved surface crack up. I didn't know nylon did that. I would like to find a plastic which can be sent through the same electroplating process as traditional metal-based lacquers, for making nickel stampers to mass-press vinyl records...

Thanks for the responses. I've ordered PVC sheets 1/16 & 1/8 to experiment with. (And, conveniently enough, also recently had a record pressing plant press up totally blank, un-grooved 7-inch and 12-inch PVC vinyl records, so will try coating a couple of those too.) I found while cleaning up...

HELP: What plastics would be most resistant to melting / warping, if a (rigid) sheet of that plastic between 1/16" and 1/8" thick was coated on both sides with a layer of thickened nitrocellulose LACQUER mixture, and left slowly rotating in a vertical position to dry? From what I've seen...
