Post Subject: Shellac contd.Posted by N-set on: 2/5/2017
Paul, thank you. Sure thing: I first solder, than clean mecanically and/or with a special solution for cleaning PCB's (KONTAKT PCC), let it dry and then apply shellac.
I dont use water after all that. I may also apply to thick a layer. Isopropyl evaporates very quickly so the bubles could be it evaporating from the deeper layers. I'll try the de-naturated alco.
Edit: Doing some chemistry homework, found that isopropyl will evaporate *slower* than ethanol. I was wrong above. So maybe thats the reason-slowly evaporates from the deep, making bubbles.
