I have contacted 3M for their fluid here in India and they do have it here but the price per gallon is a bit too, too, too, high...
I've came to the same conclusion here in Canada. Too expansive to wort the investment except if you can overclock your miners by a large factor. Next 16 nm Bitfury chips can be economicly cooled by immersion cooling. All depends as to when they will be available to the general public.
