Water-cooled spindle coolant solution

Hey all,

the main component is distilled water, which has nearly no electrical conductivity (under 2 µS/cm). There is a concentrated version available that you mix 1:2.

Ethylene glycol is what most people know as antifreeze and is what you put in the radiator of your car to prevent freezing and what is sprayed in tons per year on airplanes to deice them.

Since the corrosion inhibitor is not mentioned in the material safety data sheet, it’s probably based on Molybdic acid, Triazole and a substance that ensures a high (alkaline) pH value which require no declaration.
