METALGUARD® E-5100

WEBA Technology offers finished low-conductivity coolants for customers who do not have access to low-conductivity deionized water and/or ethylene glycol. METALGUARD® E-5100 Coolant meets ASTM D8566, the specification for low-conductivity electric vehicle coolant, which has a requirement for finished coolant with ≤100 microsiemens/cm.

METALGUARD® E-5100 Coolant can be used in electric vehicles requiring ≤100 µS/cm (microsiemens/cm). E-5100 Coolant maintains a stable, low-conductivity over long periods of time through its proprietary formulation of non-ionic corrosion inhibitors. This mechanism is essential to maintain safe operation of battery-powered vehicles in which the coolant directly contacts the battery parts.

Inhibited METALGUARD® E-5100 coolant protects aluminum, copper, brass, stainless steel, and titanium. It is compatible with most elastomers and other materials including silicon rubber, Viton, EPDM and graphite. It is not compatible with carbon steel, cast iron, or zinc/galvanized steel.

The E-5100 coolant is ready-to-use. Any non-tested deionized water for top-off, or even standard virgin glycol, may increase conductivity and reduce corrosion protection. Conventional antifreeze/coolant should never be added to E-5100, and low-conductivity coolant should never be used in internal combustion engine cooling systems. Additionally, no dye or colorant, of any type, should be added to E-5100 coolant. Even a small quantity of such ionic solutions will cause a dramatic increase in the fluid’s electrical conductivity.
