What's in a Polaroid print coater?
I looked up the MSDS for the print coater goo, and got the following info:
Isopropanol/Isopropyl alcohol, 5-15%
Zinc acetate dihydrate, 2-5%
Glacial acetic acid, 3-7%
However, not only are these percentages VERY approximate, but the MSDS is not required to list "chemicals present in the mixture in concentrations below 1% which are considered not to be a hazard", so I may be missing some essential ingredients.
Does anyone know the full ingredients list with concentrations for the Polaroid print coater? Many of the ones I find in old film boxes are dried up, even though the developer pods in the film often aren't because they're inert-gas packaged. (Why did no one think to do that with the coater?)
