Anyone know of any sponge material that is resistant to toluene? I have a spray application where the spray heads, to avoid gumming up, are immersed in toluene. This leads to a fairly large evaporation. My thought was that a sponge material would keep the heads wet with toluene, but would minimize evaporative loss. I am open to suggestions.
