RV antifreeze as non-toxic bandsaw blade coolant and opinions for blade brush.

[ironwrx]

I'm not sure about the lubricity properties of RV antifreeze. I do know that it gets sticky as it dries. We've used several different brands for over 20 years on our motorhomes and you have to make sure to wash it off your hands or any surface it gets spilled on or it makes a sticky mess when it dries. If it dries on your hands, it gets sticky again every time it gets wet again. A quick rinse with water usually washes it off.

Have you considered soluble oil emulsions like Trim-Sol? It supposedly has a freezing point of -.4*F or -18*C. I use it in my cold saw at about a 10% solution and it works great. The saw is in a heated shop, so it never experiences temperature related issues.

Here's the MSDS sheet:

The Trim-Sol sounds fine, but the oil is not the problem. Several of the water soluble oils I have used are freeze resistant, but the water is use isn’t. I guess I’ll just add a bit of oil to the RV antifreeze and go from there.
