Does anyone know of an epoxy or super glue which is a liquid? It would have to be about syrup-thick, thin enough to say, flow between microfins on a heatsink for example. It also must bond very well to metal, not break down with age or be affected by water/moisture. Epoxy seems just about perfect, but I have no idea if a liquid version exists, or of any way to liquify it during cure time without significantly weakening the bond. There are polyurethane glues like Gorilla Glue, but most people say they don't bond well to metal, and foam up, which is not what I want, as I am not wood working. Any ideas here? The only one I had was using a hard super glue that worked on solvent evaporation, then mixing some of the glue with the solvent to thin it up. With ample drying time, it should harden to the same rock solid state with the same bond strength (or close enough) as if it was plain, thick super glue.
