Hi all and again thanks to Ahmet ( from the Yahoo group )for sending a sample to me.
I have tested extensively the Adhesive backing FEP Teflon and am abandoning that
route for now. It seems to have the same problem as straight
polycarbonate/nylon/Polyethylene. It is difficult to separate the resin ( at
least mine )without it actually coming off the glass base. You could be using a
different resin with different results, but for my purposes it does not work.
Cheers!

Yellow Resin Dye
Hey All,
I have tested a few dyes and have settled on one that
proved most universal. Like many other people have mentioned it here before:
Castin' Craft dye from Environmental Technologies Inc - eti-usa.com
The only difference is the color - Opaque Yellow.
I have tried the transparent amber, yellow, blue, green.
Also I have tested Opaque red and yellow. The latter proved a good absorber or
the UV/NUV/Blue spectra per volume. It was able to limit the polymerization to a
very predictable depth no matter the exposure time. As per the instructions: use
1oz per 32oz or roughly 29gr per liter and at $6 an oz, it is perfect.I have
tested it with about 80ml of resin and 2-3ml dye and is fantastic, you have seen
the results.
