Something tells me that is not THE coating on your commercial panels

Cheers everybody and a Happy New Year
Alex
P.S. I've tried to find this particular glue for a while... no luck

6300, 6400 6500 are not for the floor - they are specified as bin and visor coatings - that's what rep told me. Need a quote?

Hi Calvin,
I read about your hobby glue recipe previously. Unfortunately the brand of glue used in your recipe is not available in the U.S. Do you know of a source in Canada?

You're of course right Alex. My Boss simply thought it'd be a rip-off from the customers if we used such a cheap coating. So I had to find and use something much more costly

@Charlie
Unfortunately I don't know of a source in Canada. I've been in Canada once for just a couple of days. Visited Calvin-tower in Toronto ....or was it cn-tower? Dunno, has been a while since then. Got my issue of Ron Wagners book there.

Here is a little study that may help with your question.

Don't use PVA and ink. I used it before. While it worked, it's too humidity dependent. The glue actually attracted moisture. When the himidity is high, it condenses into water drops.

Hi,

@Wachara
Not everybody builds submarine Headphones You know?
Iīve stored panels coated with the glue formula in a damp, open cellar for more than 10years. Every now and then I dedust and test them. So far neither temperature nor humidity or age has changed the functioning of the coating.
Itīs good to know Your experience, but this doesnīt disclude the coating alltogether, but just for certain climatic conditions.

ps. of course a homoeopathic dose of the secret ingredient guru-spoo must be added too
