Electrolube ER2223 and ER2225 epoxy resins for automotive under-hood applications

Electrolube has launched two-part epoxy resins that have been specifically formulated to cope with the harsh operating environment of under-hood requirements, offering a high degree of protection to electronic components.

ER2223 is a black epoxy resin with a wide operating temperature range of -40 to +180°C. The high-temperature-stable epoxy is chemically resistant, enduring a variety of chemicals and fluids found in the under-hood automotive environment. The low viscosity of this resin allows for easy potting of the smallest or tightly packaged components and demonstrates adhesion to a wide variety of substrates.

ER2225 is a black epoxy resin formulated to ensure an identical level of chemical resistance as ER2223, but additionally allows short temperature excursions up to +210°C. It is more viscous than ER2223 due to the inclusion of fillers that give the cured resin a thermal conductivity of 1.1 W/mK. Both resins are RoHS 2 compliant and also suitable for a variety of other electronics applications exhibiting strong resistance to thermal cycling found in engine compartments.
