I want to print a slow drying waterbase glue, does anyone have any info or recipes? I was thinking a PVA interior glue with some kind of thickening agent (to help with printing) and something to slow the drying, giving me time to wash out my screen. I want to use the printed glue to apply metal leaf so the longer it stays tacky the better. I guess an oilbase adhesive would be slower but I prefer working with water base products.
