esl diaphragm coating with Elmer's glue

[Manolo47]

So, is Elmer's PVA based ? Maybe this has been discussed here but did not find a clear answer. Working on a new diaphragm for my 988. Thanks.

Elmer's is a PVA (polyvinyl acetate) glue. I've heard of it being used as a diaphragm coating but I don't know how well it works or whether any dopants or dilution are required. Hopefully someone will post a PVA diaphragm coating recipe. Personally I would opt for Licron Crystal; although it's not cheap.

I cannot get licron here because it cannot be shipped by air, price is not the issue. The other alternative is from ER Audio from Australia. Inwas looking into a fast diy solution.

I'd go with the ER Audio solution. PVA is going to be a rough road that probably will not work out well.
