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.

E-5100 Coolant can be used in electric vehicles requiring ≤100 µS/cm (microsiemens/cm). It should not be used in conventional internal combustion engine cooling systems. 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.

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

E-5100 Coolant is ready-to-use. Addition of any non-tested deionized, or even low-conductivity glycol, may increase conductivity and reduce corrosion protection. Conventional coolant should never be added to METALGUARD® E-5100 coolant and this coolant should not be used in internal combustion engine cooling systems. Additionally no dye or colorant of any type should be added to the finished coolant. Even a small amount of such ionic solutions will cause a dramatic increase in the fluid’s electrical conductivity.
