Re: [Homebrew_PCBs] Heatless (cold) Toner Transfer for PCB making

2016-01-06 by Jean-Paul Louis

Pure Ethyl Alcohol (Ethanol) will be the hardest to find in the US. All the pharmacies in the US now carry IPA (Iso Propyl Alcohol) which is not Ethanol. 96% purity limit for current ethanol is not by accident. It is the maximum purity that you can obtain by distillation. In order to get 99%, you need to use a different process that will go beyond the 96% limit. I do not know the english name of the process.
When I was in France, 99% Ethanol was available at any pharmacy and was called “Alcool rectifié” which translate approximately by rectified alcohol.
