I'm using this kind of ink to make solder mask (actually, I brought but didn't used yet) and seller told me that the main difference between this and the ink for making PCB (traces) is that this one is with epoxy and gloss. Also, this one is multi-component.....you need to mix ink + catalyst. My question is: how can I find this kind of ink on ebay? I know that's a chinese ink, but I could not found on ebay.
