MIL-C-47220B - Dielectric Coolant Fluid
We perform quality and conformance testing by military specification MIL-C-47220, which covers silicate ester coolant fluids used in electronic applications. These coolant fluids are intended for use in as a heat transfer medium in closed systems and is capable of functioning as a dielectric fluid over a wide range of operating temperatures.
