David,
To me, what I think is needed is something that makes the coolent absorb heat
more. We have to remember that ethylene glycol and other anti-freeze products
are only for just that, keep it from freezing in the winter months. Any
addative to help with cooling would need to make the coolent abosrb more heat
than straight water itself. This I'm not sure about as I am no chemist by any
means. I do know that water is the standard all around coolent though. Adding
some form of salts as I mentioned earlier would help it not boil off too easy,
but you have a thick mess which hardens up when no heat is there to keep it
thinned. When I was doing the gun bluing, the bath has to come to a boil at 280
deg F. for regular steel and 290 deg F for a nickel steel. Using a thermometer,
I had to watch that the boiling bubbles appeared right at one of those
temperatures. If it was unser, I added more salts, over I added more water. Any
chemists could probably nail it right off.
Best,
Will
