Lacquer disc coating and raw materials.

[Maistrow]

Hello Trolls, I thought I'd just throw this out there, but I have several formulas for lacquer disc manufacturing. These are Nitro-cellulose lacquer formulas that my father had created in the late 40's for a company that manufacturing blank discs for cutting. I also have the formulas for the thinners that go along with the lacquers and a list of the raw material suppliers. I know something of this nature is only usable in a large manufacturing plant environment.

Hi,

I think this info could be useful to DIY'ers like myself. I know some here have experimented with coatings of this nature. I guess it depends how involved the formula and mixing process is. Can you post some info here or is too much involved?

hello. it would be great if you can make it public domain. or at least publish one or two receipts. i think to get some formulas as a starting point would be great. also from a historic point of view. i think for conservation of old laquer disks this is important information.

if you need a place to host the information. or have no time to publish. i am happy to put in on my website and opening a chapter. laquer production.

thanks

The formulas do not work for any type of DIY situation. Many of the raw materials used in the formula are not available to the public. Also, some of the materials are highly volatile and can be dangerous or harmful if misused and I would not want to harm anyone. It takes great skill and training to work with something of this nature. Also, the formulas are proprietary information. They are under patent and not available for public domain. obviously something of this nature can only be used in a large controlled manufacturing environment. Perhaps there may be some investors that may be interested in something like this.

Hmmm.... I see. So this is about money. I hate to be the one to tell you this but there is NO MONEY in vinyl records - people do it because they LOVE the format and we like the idea of keeping vinyl alive. You should join us!

If you had ever visited Transco to see how lacquer discs are made, producing these commercially would require a very big investment. Your formulas are nearly sixty years old and Im sure that advancements in the last sixty years would reduce any appeal from investors.

May we know which company produced lacquer discs from these formulas?

All the best in your endeavours. If you ever change your mind, you know where we are and as you can see from the responses already and the forum in general, any technical information regarding vinyl records is always appreciated here.

All the best.

Maistrow,

I already posted the most basic ingredients and how-to make your own lacquers... here's the link... but of course, any additional info you can add would be much appreciated by everyone including myself:

ron hello?

I hate all this bullshit about not giving out "secret recipies". Just like Nuemann wouldnt give out any information about thier cutter heads. And now people struggle with them. And laqcuer formulas are kept secret. Fair enough in the 50's because it was big money then, but now?

i think if the formulas are from the 40ies or 50ies the ip (patent) protection is long gone. so they are even published somewhere...its just hard to find them.
i think the main interest is historic. to understand the different formulas. and as i said for archive or restauration people it would be good. so archives with lots of laquers could understand whats best way to store the laquers. or to preserve them.

commercially there is no money to get.

[blacknwhite]

Flo, you mentioned that the chemical analysis of the old (1950s) lacquer formulas would be of historic value for preservation.... that's where I got the info for the how-to instructions I posted. That's the only info I ever found, and I talked to a number of lacquer disc preservationists too.

But the article was written with the aid of chemists, studying many different brands of discs, so I trust that the nitro lacquer & castor oil were the only "important" ingredients.

I scoured the US patent database for info, looking through all kinds of searches like "recording blanks", etc., and still, couldn't find any. But I'm ordering a technical book from Amazon with specific instructions for engineers and lawyers of the best ways to search the patent database, so I'll try again after I get that:
